Abstract
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).
