PROBLEM TO BE SOLVED: To provide a metallized film for a capacitor and a capacitor using the same capable of obtaining high moisture resistance.SOLUTION: A metallized film obtained by forming a metal layer on one side of a polypropylene film is a metallized polypropylene film for a capacitor in which a silicone oil layer or a fluorine oil layer of 0.02 to 0.2 μg/cmis formed on the surface of the metal layer, and a wetting index is 33 to 50 mN/m, a wetting index of the surface opposite to the metal layer of the polypropylene film is 33 to 45 mN/m, and the charge amount is in the range of -15 to +15 V.SELECTED DRAWING: None 【課題】高い耐湿性を得ることのできるコンデンサ用金属化フィルム、およびそれを用いたコンデンサを提供すること。【解決手段】ポリプロピレンフィルムの片面に金属層を形成してなる金属化フィルムであって、該金属層の表面に０．０２〜０．２μｇ／ｃｍ２のシリコーンオイル層もしくはフッ素オイル層が形成されており、かつぬれ指数が３３〜５０ｍＮ／ｍであり、ポリプロピレンフィルムの金属層と反対側の面のぬれ指数が３３〜４５ｍＮ／ｍであり、帯電量が−１５〜＋１５Ｖの範囲であるコンデンサ用金属化ポリプロピレンフィルムである。【選択図】なし
