In addition to excellent wear resistance, when applied to an electronic component such as a capacitor or an electrophotographic photoreceptor as a coating, corrosion of the metal is suppressed even during long-term use, and excellent electrical characteristics are maintained. Provided is a resin for forming a film. A film-forming resin comprising a polyester composed mainly of a divalent carboxylic acid residue having a biphenyl, diphenyl ether or cyclohexane ring residue and a divalent phenol residue, which is free A film-forming resin containing 0.01 to 300 ppm of a divalent carboxylic acid.
