More specifically, the capsule member 23 is formed of, for example, a polyethylene resin material, but may be formed of other kinds of resin materials (synthetic resin materials), such as polypropylene, polyurethane, polyvinyl chloride, and the like.
  • the melting point of the capsule member 23 formed of polypropylene for example, is 104 to 120° C., which is lower than the melting point of the thermoplastic resin (hot-melt adhesive) of 150 to 180° C. Therefore, when the thermoplastic resin (hot-melt adhesive) is used as the adhesive 24 , there is a possibility that a hole may be formed in the capsule member 23 when the thermoplastic resin is melted.
