A liquid photocurable composition containing a photopolymerizable polyurethane compound having a repeating unit represented by the following formula: B-[X]n[Y]m-B, where X is represented by the formula:and Y is represented by the formula: -OOCHN-A-NHCOO(R2)-, A is a structural unit derived from a polyisocyanate compound, B is same or different and a structural unit derived from a hydroxy compound having at least one photopolymerizable unsaturated group at molecular terminals respectively and optionally containing an ether linkage, R1 is a structural unit derived from a carboxyl group-containing polyol compound, R2 is a structural unit derived from a polyol compound, n is an integer of 1 to 10, m is an integer of 1 to 10, provided that one X and one Y are bonded to each other, or three or more of X and/or Y are bonded to each other, and optionally containing a photopolymerizable compound other than the photopolymerizable polyurethane compound.
