<p>PROBLEM TO BE SOLVED: To provide a photocurable resin composition giving a cured product which has low moisture permeability, facilitates rework, and has high compressive breaking strength and excellent flexibility.SOLUTION: The photocurable resin composition contains: (A) a photocurable resin having a constituent unit derived from a diene compound and having (meth)acryloyl groups at both terminals; (B) a photocurable monomer having a non-conjugated cyclic hydrocarbon group and a (meth)acryloyl group; (C) a photocurable monomer represented by general formula (1); and (D) a photopolymerization initiator. A sealing material is formed by irradiating the photocurable resin composition with a light beam. [In the general formula (1), R represents a hydrogen atom or a methyl group, and A represents a C10-C22 acyclic hydrocarbon group having at least one branched structure.]</p> |
