Abstract
A photocurable material that allows dark portion curing even if the form of a material to be cured is complicated and the length of an unirradiated portion is long. The photocurable material has both of radical curability and anionic curability, is a photocurable liquid composition curable by irradiation of light, and contains (meth)acrylate and a chain transfer agent, wherein the chain transfer agent is a compound containing one or more of at least one kind selected from a urethane bond, a urea bond, and an isocyanate group, and one or more alkoxysilyl groups. The photocurable material is capable of curing even a portion that irradiation light does not reach.
