Abstract

Provided is a photocurable composition including a monomer component including: a monomer (X) containing, within one molecule, two aromatic rings and two (meth)acryloyloxy groups, and having an Mw of from 400 to 580, and a monomer (H) containing, within one molecule, at least one of a hydroxyl group or a carboxy group, and a (meth)acryloyloxy group, and having an Mw of from 100 to 700; and a photopolymerization initiator. The composition has a functional group value (a) of from 0.5×10to 2.0×10mol/g.Functional group value ()=()×  Formula (a)wherein nrepresents the total number of hydroxyl groups and carboxy groups contained in one molecule of the (meth)acrylic monomer (H); Mrepresents the Mw of the (meth)acrylic monomer (H); and Prepresents the mass ratio of the (meth)acrylic monomer (H) with respect to the total amount of the (meth)acrylic monomer component.
