PROBLEM TO BE SOLVED: To provide a film that has no the film from peeling of a capacitor surface, displaying an excellent withstand-voltage property and being capable of improving a working yield, when manufacturing a laminated film capacitor. SOLUTION: In a biaxially-oriented polyphenylene sulfide film for the capacitor, the number of projection structures having an aspect ratio of 5 to 30 are 10 to 50 per 10,000μm<SP>2</SP>in the projection structures forming undulated projections on the film surface of at least one surface while having heights of 250 nm or larger and short diameters of 2μm or larger, in cross sections, having heights of 250 nm.
