Abstract:
The present invention addresses the problem of providing a biaxially stretched polypropylene film for capacitors, which has high voltage resistance and excellent breakdown properties. The present invention also addresses the problem of providing a biaxially stretched polypropylene film for capacitors, which can be used suitably in a high-capacity capacitor to which a high voltage is to be applied under a higher temperature, and which preferably has a small thickness. The present invention relates to a biaxially stretched polypropylene film for capacitors, wherein a polypropylene resin which constitutes the polypropylene film has a number average molecular weight of 40,000 to 100,000 inclusive and a Z average molecular weight of 950,000 to 1,500,000 includes wherein, in a molecular weight distribution curve, the value of the difference obtained by subtracting a differential distribution value at a logarithmic molecular weight Log (M) of 6.0 from a differential distribution value at a logarithmic molecular weight Log (M) of 4.5 is −15 to 11% inclusive.

Claim (Index 3):
The biaxially stretched polypropylene film for capacitors according to  claim 1 , wherein the polypropylene resin composing the polypropylene film has a molecular weight distribution Mw/Mn of 6 or more and 12 or less, which is calculated as the ratio of the weight average molecular weight Mw to the number average molecular weight Mn of the polypropylene resin constituting the polypropylene film.
