Abstract: A photocurable composition contains:
a component (A): (meth)acrylic acid ester having 2 to 6 (meth)acryloyl groups in one molecule,
a component (B): a thiol compound having 2 to 4 thiol groups in one molecule, and
a component (C): a photobase generator,
in which a mass ratio of the component (A) to the component (B) is 66:34 to 33:67, inclusive,
a functional group equivalent of the component (A) is 96 g/eq to 180 g/eq, inclusive,
a functional group equivalent of the component (B) is 95 g/eq to 190 g/eq, inclusive, and
a content of the component (C) is 0.5 parts by mass to 2 parts by mass with respect to 100 parts by mass of a total of the component (A), the component (B), and the component (C).
