ABSTRACT:
A freely peelable release part structure is disclosed. The tape or a like part associated with the structure is difficult to separate when it should be kept fixed. On the other hand, noise-free peeling thereof is easy when it should be peeled away. In particular, a release part structure useful for the fastening of diapers is provided. It contains a structure of a release part whose interfacial boundary is constituted by a pressure-sensitive adhesive layer (4) and a silicone-based release layer (2), characterized in that the adhesive layer comprises a tacky substance containing a rubber as a major component and the release layer comprises a silicone-based release agent containing a three-dimensional structure organopolysiloxane in an amount of 1-80% by weight.
