Beschreibung
Zusammenfassung:	Provided are a biaxially oriented polypropylene film having excellent withstand voltage characteristics at room temperature and high temperature, a metal film-laminated film, and a film capacitor. The present invention includes a biaxially oriented polypropylene film including a polypropylene resin as a main component, in which a first melting peak Tm1 existing at the highest temperature side in a first temperature rising curve obtained by measuring melting peaks using DSC is 176°C to 180°C.
