The present invention relates to a photosensitive resin composition capable of forming an electric insulating layer by forming a film, exposing the film and then thermosetting, and suppresses wrinkling of the electric insulating layer. A photosensitive resin composition that can be used is provided. The photosensitive resin composition of the present invention comprises a carboxyl group-containing unsaturated resin (A), a colorant (B), a photopolymerization initiator (C), a photopolymerizable compound (D), Containing an epoxy compound (E). The carboxyl group-containing unsaturated resin (A) includes a carboxyl group-containing unsaturated resin (A1) containing at least one of a cresol novolak skeleton and a phenol novolak skeleton and a urethane bond.
