PROBLEM TO BE SOLVED: To provide a resin composition which is prepared by using a novel oligomer having a high performance/a high function, especially one having stiffness, heat resistance, and flexibility, is excellent in developability, photosensitivity, and surface curability, and gives a cured item excellent e.g. in resistances to solvents, acids, and heat; and a cure item thereof. SOLUTION: This resin composition contains an oligomer (A) and a cross- linker (B). The oligomer (A) is prepared by reacting an epoxy compound (a) having at least two epoxy groups and exhibiting liquid crystalline properties with a monocarboxylic acid (b) having at least one double bond and reacting the resultant epoxy carboxylate compound (c) with a polybasic acid anhydride (d) having two acid anhydride groups and, optionally, a polyol compound (e).
