    摘要: The present invention provides a high dielectric film for a film capacitor obtained by molding a film forming composition for a film capacitor comprising a thermoplastic resin (A) and surface-treated high dielectric inorganic particles (B) obtained by treating the surfaces of high dielectric inorganic particles (b1) having a dielectric constant (20° C., 1 kHz) of 100 or more with a low dielectric compound (b2) having a dielectric constant (20° C., 1 kHz) of 10 or less. This high dielectric film for a film capacitor can restrain the decrease of electrical insulating property, in spite of the high dielectric inorganic particles being dispersed at a high filling rate.
