Provided is a photosensitive composition which can be cured with low energy consumption, even when a substance (such as a colorant) that attenuates or shades an illumination light is contained in a high concentration or even when the photosensitive composition is in the form of a thick film. Specifically provided is a photosensitive composition which comprises the following four components: (1) a radical initiator (A); (2) an acid generator (B) or a base generator (C); (3) a polymerizable substance (D); and (4) a colorant (E), a metal oxide powder (F), or a metal powder (G). Further, the photosensitive composition is characterized in that the radical initiator (A), the acid generator (B), and/or the base generator (C) generates an active species (H) through irradiation with an active ray of light; the active species (H) reacts the radical initiator (A), the acid generator (B), or the base generator (C) to form another species (I); and thus the polymerization of the polymerizable substance (D) by means of the active species (I) proceeds, said active species (H) or (I) being an acid or a base.
