Photocurable adhesive composition, pressure-sensitive adhesive sheet, and the laminate

In the bonding step of the substrate surface having irregularities, without using a heat treatment or pressure treatment with it is possible to suppress the generation of air bubbles, to a technique regarding excellent adhesive on the adhesive strength and optical properties. (A) (meth) relative to 100 parts by mass of the acrylic polymer, (B) 10 to 50 parts by weight of the monofunctional monomer having a cyclic structure, 0.1 to 10 parts by weight of (D) a photopolymerization initiator, ( E) providing a photocurable adhesive composition comprising a thermal crosslinking agent at a content ratio of 0.5 to 10 parts by weight.
