실온 및 고온 내전압 특성이 우수한 2축 배향 폴리프로필렌 필름, 금속막 적층 필름 및 필름 콘덴서를 제공하는 것. 본 발명은, 폴리프로필렌 수지를 주성분으로 하는 2축 배향 폴리프로필렌 필름으로서, DSC를 사용하여 융해 피크를 측정한 경우의 1회째의 승온 커브에서 가장 고온측에 존재하는 제1 융해 피크 Tm1이, 176 내지 180℃인 2축 배향 폴리프로필렌 필름이다. 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.
