Abstract:
There is a film capacitor capable of suppressing decrease in the electrostatic capacitance even after a self-healing phenomenon has occurred. A film capacitor includes a dielectric film; and an electrode film disposed on a principal surface of the dielectric film, the dielectric film containing an organic resin and an organic component having a higher volatility than the organic resin. The organic resin is preferably any one of a cyclic olefin-based resin, a polyarylate resin, a polyphenylene ether resin and a polyetherimide resin. The organic component is preferably at least one selected from the group consisting of cyclohexane, ethylcyclohexane, toluene, xylene, chloroform, and tetrahydrofuran.
