That is, even if the outer layer sheet 12 is twitched or distorted due to an external force applied by the outer garment during the wearer's operation, the external force that causes the outer layer sheet 12 to twitch or distort due to the presence of the floating portion G. It is difficult to be transmitted to the inner layer sheet 13. Therefore, an external force suppresses the movement and deformation of the diaper such as displacement, and an excellent wearing feeling or the like is obtained. Moreover, when the floating part G arises, the external appearance of the diaper 1 will give a soft impression, and the aesthetics of the diaper 1 will improve.
  • the waist elastic member 51 and the lower elastic member 91 that contract in the waistline direction exist above and below the floating portion G. Therefore, the three-dimensional formability of the floating part G is excellent. Moreover, since the sheet or the like located on the skin surface side of the floating portion G is fixed in close contact with the skin by the inner elastic member 71, the floating portion G is less likely to be unevenly anteroposteriorly and laterally, and the three-dimensional structure of the floating portion G Formability is not easily impaired. For this reason, the external force buffering effect by the floating portion G is reliably exerted even when walking or standing or sitting, etc., and a decrease in wearing feeling or the like is prevented.
