摘要
A metallized film which is little broken near the margin even if high voltages specified to be applied by safety standards for capacitors are applied and can be used to produce a very highly safe capacitor is disclosed, together with a production method thereof and a capacitor with excellent performance. The present invention relates to a metallized film, comprising a deposited metal layer zone (4) destined to be an electrode with a surface resistance of 1 OMEGA /sq. - 15 OMEGA /sq., a margin with a surface resistance of 1 x 1010 OMEGA /sq. or more, and a 0.02 to 1 mm wide boundary zone (3) existing between the deposited metal layer zone (2) and the margin and continuously decreasing in the thickness of the deposited metal layer from the deposited metal layer zone (9) to the margin, at least on one side of a high polymer film. The present invention also relates to a capacitor produced by winding into a roll the metallized film or stacking it with other identical metallized films. IMAGE
