Provided is a photopolymerizable composition that is highly sensitive to light having wavelengths of 365 nm and 405 nm, and is capable of forming a curable film that can suppress deterioration in physical properties of the film due to heat-aging. The photopolymerizable composition include: (A) an oxime polymerization initiator which includes a condensed ring formed by containing two or more rings selected from an aromatic ring and a heterocyclic ring, and a cyclic structure which is connected to the condensed ring, the cyclic structure containing a carbonyl group and having an oxime group directly connected to the carbonyl group; and (B) a polymerizable compound.
