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 0.5×10−3 to 2.0×10−3 mol/g.Functional group value (a)=(nH/MH)×PH Formula (a)wherein nH represents the total number of hydroxyl groups and carboxy groups contained in one molecule of the (meth)acrylic monomer (H) MH represents the Mw of the (meth)acrylic monomer (H) and PH represents the mass ratio of the (meth)acrylic monomer (H) with respect to the total amount of the (meth)acrylic monomer component.
