Abstract
A resin composition constituting dielectric resin films of a film capacitor includes a first atom group including at least one functional group selected from among a methylene group, an aromatic ring and an ether group and having a relatively small molar polarizability, and a second atom group including at least one functional group selected from among a hydroxyl group, an amino group and a carbonyl group and having a relatively large molar polarizability. The resin composition satisfies the condition that a value calculated from the formula (sum of absorption band intensities of first atom group)/(sum of absorption band intensities of second atom group) is 1.0 or more. Herein, as absorption band intensities of the functional groups, peak intensities detected in specific wavenumber ranges are employed.
