To provide a photosensitive composition curable with a small energy amount even when a substance such as a colorant attenuating or shielding an emitted light is present in high concentration or even when a film is thick.

A photosensitive composition contains the following (1) to (3): (1) a radical initiator (A), or a radical initiator (A) and an acid generator (B); (2) a base generator (C); and (3) a polymerizable substance (D). At least one of the radical initiator (A), the acid generator (B) and the base generator (C) generates active species (H) by irradiation with an actinic ray; the active species (H) is reacted with the radical initiator (A), the acid generator (B) or the base generator (C) to generate new active species (I); polymerization reaction of the polymerizable substance (D) by the new active species (I) proceeds; the active species (H) or (I) is an acid or a base; and polymerization reaction of the polymerizable substance (D) proceeds by a base generated by irradiating the base generator (C) with an actinic ray in parallel with the above polymerization reaction.
