The curable resin composition of this invention contains a carboxyl group-containing photosensitive resin, a photoinitiator, and a thermosetting compound. This carboxyl group-containing photosensitive resin contains a radically polymerizable polymer. The radically polymerizable polymer contains, in the polymer as a base polymer, a structural unit derived from a maleimide-based monomer, a structural unit derived from an unsaturated carboxylic acid monomer not having an ester bond, A structural unit derived from a monomer having a hydroxyl group is an essential unit, and the radically polymerizable polymer has a structure in which a carboxyl group, which is a polymer of the base polymer, has a monomer having a functional group reactive with the carboxyl group. The structure formed by the reaction of the body. |
