PROBLEM TO BE SOLVED: To provide a resin composition, which incorporates a new oligomer having a high performance and a high functionality, particularly an oligomer that has a high rigidity and a heat resistance as well as a flexibility, which is hence excellent in developability, photosensitivity and surface hardening properties, and whose cured product is excellent in solvent resistance, acid resistance, heat resistance and the like, and provide a cured product thereof. SOLUTION: There is provided a resin composition comprising an oligomer (A) and a crosslinking agent (B), the oligomer (A) being obtained by reacting a polyimide precursor (a) having a terminal anhydride group or a reaction product of (a) and a polyol compound (b) with an epoxycarboxylate compound (c) obtained by reacting an epoxy compound (c-1), which has two epoxy groups in the molecule and exhibits a liquid crystallinity, with a monocarboxylic acid (c-2) having one or more unsaturated double bonds in the molecule. |
