PROBLEM TO BE SOLVED: To provide a photosensitive composition having a high bonding strength even under the presence of a fine amount of water content. SOLUTION: This curable composition contains≥1 kind selected from a group consisting of a butylene polymer, a copolymer of butylene with another polymerizable monomer, a butadiene polymer and a copolymer of butadiene with another polymerizable monomer, and also an unsaturated carboxylic acid ester having hydroxy group in its molecule, a photosensitizer and a silane-coupling agent, and preferably contains a multi-functional vinyl monomer. Preferably, the≥1 kind selected from the group consisting of the butylene polymer, a copolymer of butylene with another polymerizable monomer, a butadiene polymer and a copolymer of butadiene with another polymerizable monomer has one of a hydrogenated 1, 2-polybutadiene terminal urethane acrylate or 1, 2-polybutadiene terminal urethane acrylate.
