Provided is an adhesive composition, which can prevent misregistration in bonding adherends to each other, can firmly bond adherends to each other as such in the case where no modification is needed in bonding, and easily allows the separation of the adherends from each other, without damaging the adherends, in the case where modification is needed in bonding. Also provided is a method for producing a laminate using the adhesive composition. The aforesaid adhesive composition contains a main adhesive agent, which comprises a monomer, and a polymerization initiator. The adhesive force of the adhesive composition varies in such a manner that the maximum value, the minimum value and a value exceeding the maximum value appear with an increase in the irradiation amount of an electromagnetic wave or a particle beam in a definite temperature environment. In the aforesaid method for producing a laminate, an adhesive composition layer can be easily separated from an adherend when the adhesive force of the adhesive composition attains the minimum value.
