Zusammenfassung:	A method for releasing an adherend of the present invention includes a first step and a second step. In the first step, a bonded product (100) including a pressure-sensitive adhesive layer (10), and an adherend (20) bonded thereto is prepared. The pressure-sensitive adhesive layer (10) includes a pressure-sensitive adhesive component and a gas generating agent. In the second step, a laser light (L) is irradiated to the pressure-sensitive adhesive layer (10)-side of the bonded product (100) to heat a part of the pressure-sensitive adhesive layer (10). A pressure-sensitive adhesive composition of the present invention is a composition used for forming the pressure-sensitive adhesive layer (10) in the method.
