Disclosed is a photopolymerizable composition which contains a photopolymerization initiator (A) that has a partial structure represented by the following Formula (1) and a polymerizable compound (B). In General formula (1), R 3 and R 4 each independently represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heteroaryl group or an alkoxy group; R 3 and R 4 may form a ring with each other; and X represents OR 5 , SR 6 , or NR 17 R 18 . The photopolymerizable composition is capable of forming a cured film that has high sensitivity, excellent infra-membrane curability and excellent adhesion to a support. The cured film is able to maintain a patterned shape even during post-heating after development and has good pattern formability, while coloring due to heating with passage of time being suppressed. |
