  • the flavor components contained in tobacco can be provided to the user.
  • Specific tobacco that can be contained in the flavor sheet 81 includes shredded dried tobacco leaves, ground leaf tobacco, or tobacco extract (extract from water, an organic solvent, or a mixed solution thereof).

  • the filling amount of the flavor sheet 81 in the flavor generating body 80 is preferably 50 mg or more and 300 mg or less. If the filling amount of the flavor sheet 81 is less than 50 mg, there is a risk that the filling amount is too small to generate sufficient flavor. On the other hand, if the filling amount of the flavor sheet 81 is more than 300 mg, there is a risk that the size of the flavor generating body 80 will be too large, or that there will not be enough air flow paths to efficiently release the flavor. Therefore, if the filling amount of the flavor sheet 81 is within the above range, it is possible to generate sufficient flavor while suppressing the size of the flavor generating body 80.
  • the ratio of the surface area of the flavor sheet 81 to the surface area of the outer surface of the support 82 is preferably greater than 2 and less than or equal to 16. If the ratio is less than or equal to 2, there is a risk that sufficient vapor or aerosol cannot be generated in the flavor sheet 81. On the other hand, if the ratio is greater than 16, there is a risk that the flavor sheet 81 will be packed too densely, resulting in a reduced amount of aerosol delivered. Therefore, when the surface area of the flavor sheet 81 is within the above range, it is possible to suppress a reduction in the amount of aerosol delivered while still generating sufficient vapor or aerosol.

In this case, since the support 82 is formed from paper, the support 82 can be easily processed or formed, and can be easily disposed of after use of the smoking article 110. However, the support 82 is not limited to this, and may be solid, or may have any other shape that can support the flavor sheet 81.

Therefore, when the basis weight of the cover sheet 83 is in the above range, it is possible to suppress aerosol leakage and difficulty in processing the cover sheet. In addition, it is preferable that the density of the cover sheet 83 is 0.5 gsm or more and 1.5 gsm or less.

  • the porosity of the space S1 (see FIG. 2(b)) between the support 82 and the cover sheet 83 is preferably 20% or more and 50% or less. That is, when only the flavor sheet 81 is disposed between the support 82 and the cover sheet 83 as shown in FIG. 2, the porosity of the flavor sheet 81 is preferably 20% or more and 50% or less. If the porosity is less than 20%, the steam or aerosol generated in the flavor sheet 81 will have difficulty passing through the space S1, and there is a risk that the steam or aerosol cannot be delivered to the user efficiently.
  • the porosity is more than 50%, the volume of the flavor sheet 81 in the space S1 will be too small, and there is a risk that the steam or aerosol cannot be generated sufficiently.

In this case, it is possible to inhibit air from the tip of the smoking article 110 from flowing straight into the gap portion 114. It is more preferable that the inhibition portion 142 overlaps with the entire gap portion 114 when viewed in the longitudinal direction of the smoking article 110.

In this case, the amount of air flowing in from the tip of the smoking article 110 can be increased, so that more aerosol generated by the flavor source 81 can be supplied.
  • the size of the gap between the support portion 56 and the outer periphery of the smoking article 110 as viewed in the longitudinal direction is R, and the radial thickness T of the flavor source 81 shown in FIG. 2 is T>R, T may be satisfied.

Even when the inhibition portion 142 is filled into the recess 143, the inhibition portion 142 may be provided so as to protrude (or protrude) from the recess 143. In the example shown in FIG. 10, the inhibition portion 142 is filled into the recess 143 so as to substantially coincide with the recess 143.

  • the high density portion 142a may constitute the inhibition portion 142. This prevents air from flowing from the low density portion 144 to the high density portion 142a, so that the inhibition portion 142 can be formed by the tip plug 140 alone, without attaching another member to the tip plug 140.
  • the smoking article 110 has the inhibition portion 142
  • the ratio of the amount of air passing through the flavor source 81 in a given time to the amount of air passing through the gap portion 114 in a given time when the user inhales on the smoking article 110 is 1:0 to 1:3.
