Abstract:
1. A film capacitor comprising a wound body of a high dielectric film having an electrode formed on a surface thereof, said high dielectric film having a thickness of not more than 6 μm obtained by coating a coating composition on a substrate, drying to form a film and separating the film from the substrate, said coating composition comprising: (A) a thermoplastic non-fluorine-containing polymer, (B) inorganic ferroelectric particles, (C) at least one affinity-improving agent selected from the group consisting of a coupling agent and an epoxy group-containing compound, and (D) a solvent wherein the inorganic ferroelectric particles (B) are contained in an amount of 50 to 200 parts by mass and the affinity-improving agent (C) is contained in an amount of 0.01 to 30 parts by mass based on 100 parts by mass of said thermoplastic non-fluorine-containing polymer (A), and said thermoplastic non-fluorine-containing polymer (A) is polycarbonate or cellulose acetate, and the epoxy group-containing compound is a compound represented by the formula (C-3): wherein R is hydrogen atom, a monovalent hydrocarbon group having 1 to 10 carbon atoms which may have oxygen atom, nitrogen atom or carbon-carbon double bond, or an aromatic ring which may have a substituent; 1 is 0 or 1; m is 0 or 1; n is 0 or an integer of 1 to 10.
