Abstract: PROBLEM TO BE SOLVED: To manufacture a metallized film capacitor having defective ratio of breakdown voltage of the capacitor by specifying surface roughness and thickness of a biaxially oriented film substantially made of poly-p- phenylenesulfide. SOLUTION: Surface roughness SRmax of a biaxially oriented film substantially made of poly-p-phenylenesulfide(PPS) is a range of 1000 to 15000 nm. If the PPS film having a surface roughness SRmax or 1000 nm or more is used, repair by voltage treatment can be effectively executed. If the PPS film having a surface roughness SRmax of 15000 nm is used, a gap between film layers when the film is wound or wound by many layers or laminated can be increased to increase unevenness of electrostatic capacity of a capacitor. And, the PPS film having a thickness of 10 μm or less is an object and the PPS film having a thickness of 6 μm is an object.
