Abstract
A photocurable resin composition includes a reactive monomer, a reactive oligomer, and a photopolymerization initiator. A cured product of the reactive monomer has a glass transition point of less than 20° C., and a cured product of the reactive oligomer has a glass transition point of less than 20° C. A cured product of the photocurable resin composition has a loss tangent tan δ at 25° C. of 0.2 or less. The cured product of the photocurable resin composition has an elongation at break in accordance with ASTM D638 of 150% or more.
