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.

摘要： Provided is a film for a film capacitor in which electrical insulation, and especially electrical properties at high temperatures are improved while a high dielectric constant of a vinylidene fluoride resin is maintained. The film for a film capacitor includes a tetrafluoroethylene resin (a1) that includes a vinylidene fluoride unit and a tetrafluoroethylene unit in the vinylidene fluoride unit/tetrafluoroethylene unit ratio (mol%) of 0/100 to 49/51 as a film-forming resin (A).
