Abstract
A film capacitor that includes: a dielectric film; and a metal layer on at least one surface of the dielectric film. The dielectric film is a resin film made of a cured product of a first organic material having multiple hydroxy groups in a molecule and a second organic material having multiple isocyanate groups in a molecule. An intensity ratio of a first peak at 1680 cmto 1770 cmderived from carbonyl groups in urethane bonds to a second peak at 1560 cmto 1620 cmderived from aromatic rings in a Fourier-transform infrared spectroscopy (FT-IR) spectrum of the resin film is 0.50 to 0.94.
