PROBLEM TO BE SOLVED: To provide a photocurable composition that secures adhesive force to materials such as polyphenylene sulfide, engineering plastic excellent in dimensional accuracy but not easy for adhesion, and can maintain the adhesive force even in a moisture resistance test.SOLUTION: A photocurable composition comprises (A)-(D) components, wherein, based on the (A) component 100 pts. mass, the total of the (B) component, the (C) component and a (meth) acryl monomer excluding the (C) component is 50-200 pts. mass, and its cured product has a glass-transition temperature of 100°C or more. The (A) component is a (meth) acryl monomer polymer having a (meth) acryl group, the (B) component is an acryloyl morpholine, the (C) component is a dicyclopentanyl (meth) acrylate, and the (D) component is a photoinitiator. |
