Provided is a resin and a resin composition that are easily synthesized and patterned, and that sufficiently provide characteristics such as flame retardancy, heat resistance, mechanical characteristics, and flexibility. The resin is a phenolic hydroxyl group-containing polyimide resin obtained by condensation polymerization of (a) a tetrabasic acid dianhydride, (b) an aminophenol compound that has at least two amino groups and at least one phenolic hydroxyl group in a molecule, and (c) a diamino compound. In the phenolic hydroxyl group-containing polyimide resin, at least 5 mol% of tetrabasic acid dianhydride (a) is one or more alicyclic tetrabasic acid dianhydrides selected from the group comprising formula (1). |
