Abstract:
Disclosed is a biaxially oriented polypropylene film which has projections on both surfaces of the film. The most common height (PhZ) of the projections among the projections on each surface is 100 nm or more but less than 400 nm on each surface, and the number of projections (Pc) per 0.1 mm2 of each surface is 150 projections or more but less than 500 projections on each surface. The biaxially oriented polypropylene film is easily processed into an element, and provides a capacitor that has high withstand voltage and excellent squealing characteristics when processed into a capacitor.
