PROBLEM TO BE SOLVED: To provide a photocurable composition that includes a reaction product of a urethanization reaction obtained by performing a urethanization reaction of a hydroxyl group-containing photopolymerization initiator and that can form a cured body excellent in curability in spite of a small quantity of the hydroxyl group-containing photopolymerization initiator used for achieving the urethanization reaction.SOLUTION: A photocurable composition includes a reaction product of an urethanization reaction, obtained by performing a reaction of: a hydroxyl group-containing photopolymerization initiator; a hydroxyl group-containing α,&bgr;-unsaturated carboxylic acid ester; an isocyanate compound containing at least two isocyanate groups in a molecule; and an aliphatic polyetherpolyol compound containing two or more ether groups in a molecule. |
