PROBLEM TO BE SOLVED: To eliminate heat defeat and film breakage in a deposition working process and to improve a processability in a capacitor manufacturing process. SOLUTION: A polyphenylene sulfide film roll is formed of a polyphenylene sulfide film whose film longitudinal thermal elongation percentage is 0.1% or less, and winding solidity at a winding length of 3,000 m or more and 30,000 m or less and a winding length of 3,000 m before and after heat treatment is 86° or more and 95° or less. The capacitor is formed by winding or laminating a metallized polyphenylene sulfide film which is formed by depositing a metallic layer in one or both sides of the polyphenylene sulfide film roll.
