Abstract
A photocurable composition exhibits favorable adhesion force to an adherend, and favorable durability upon compression of a cured product thereof. A photocurable composition contains the following components (A) to (D), component (A): a polyisobutylene compound having a (meth)acryloyl group in a molecule; component (B): a urethane-modified (meth)acrylate oligomer, excluding the component (A); component (C): a monomer having a (meth)acryloyl group, excluding the component (A) and the component (B); and component (D): a photoinitiator. A content of a monomer having an alicyclic structure and a (meth)acryloyl group is 6 to 20 mass % based on 100 mass % of a total amount of the component (C).
