PROBLEM TO BE SOLVED: To provide a light resistant resin composition having excellent retention characteristics of voltage resistance property for a long time to inevitable illumination in daily application. SOLUTION: The light resistant resin composition contains a light stabilizer and a cured resin film of the resin composition having 0.05-20μm film thickness satisfies ≥150kV/mm dielectric breakdown voltage after 500 hours treatment by irradiation with a xenon arc lamp.
