Film capacitor and connection type capacitor, inverter, and electric-powered vehicle

A connection type capacitor, comprising:

• a plurality of film capacitors, the film capacitors each including:
• 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 being any one of a cyclic olefin-based resin, a polyarylate resin, a polyphenylene ether resin and a polyetherimide resin,
• the organic component containing any one of cyclohexane, ethylcyclohexane, toluene, xylene, tetrahydrofuran, and n-methylpyrrolidone, chloroform, and a mixture of cyclohexane and toluene,
• a content of the organic component contained in the dielectric film being 0.01 to 7 mass %;
• and
• a bus bar connecting the plurality of the film capacitors.
