Abstract:
1. A dielectric resin composition for a film capacitor, the dielectric resin composition comprising: 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 first 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 second molar polarizability, wherein the first molar polarizability is smaller than the second molar polarizability, and with respect to absorption band intensities of the functional groups, a value calculated from a formula (sum of absorption band intensities of the first atom group)/(sum of absorption band intensities of the second atom group) is 1.0 or more, when as the absorption band intensity resulting from the methylene group, an intensity of a peak of a methylene group on a lowest wavenumber side of 4 peaks detected in a wavenumber range of 3000 to 2900 cm as the absorption band intensity resulting from the aromatic ring, an intensity of a peak detected in a wavenumber range of 1650 to 1550 cm as the absorption band intensity resulting from the ether group, intensities of two peaks detected in a wavenumber range of 1150 to 1050 cm as the absorption band intensity resulting from the hydroxyl group, an intensity of a peak detected in a wavenumber range of 3700 to 3400 cm as the absorption band intensity resulting from the amino group, an intensity of a peak detected in a wavenumber range of 3400 to 3200 cm as the absorption band intensity resulting from the carbonyl group, an intensity of a peak detected in a wavenumber range of 1750 to 1650 cm
