Abstract
A biaxially oriented polypropylene film has projections on both surfaces of the film, wherein the height of the most common projection (PhZ) among the projections on each surface is not less than 100 nm and less than 400 nm on both surfaces, and the number of projections per 0.1 mm(Pc) on each surface is not less than 150 and less than 500 on both surfaces. The biaxially oriented polypropylene film is easily processed into an element and that, when processed into a capacitor, provides a capacitor having high withstand voltage characteristics and excellent noise characteristics.
