Zusammenfassung:A photocurable resin composition includes: a first reactive compound that forms a glass phase through curing; a second reactive compound that is compatible with the first reactive compound and forms a rubber phase through curing; and a photopolymerization initiator. The first reactive compound includes at least a reactive monomer, and the second reactive compound includes at least a reactive oligomer. A polar term dP1 of Hansen Solubility Parameter of the first reactive compound and a polar term dP2 of Hansen Solubility Parameter of the second reactive compound differ by 1.8 or more.
