PROBLEM TO BE SOLVED: To improve heat resistance and performance for a metallized film capacitor used for various kinds of electronic equipment. SOLUTION: A metal deposited electrode 1a, and a division electrode 2a via slits 4a, 5a are formed on a dielectric film. Fuses 6a, 7a, 8a are provided at one portion in the slits 4a, 5a, and a pair of metallized films, where the division electrode 2a is connected to the metal deposited electrode 1a in parallel, are overlapped for winding. The longitudinal slit 5a, which composes the division electrode 2a of the metallized film capacitor in which a demountable electrode is provided at both ends, is formed in a bellows shape. As a result, the heat resistance is improved since overlapping electrode patterns do not become the same, and hence heat generation does not concentrate in the same portion, thus preventing the slit 5a from continuing on the same line, and thereby preventing a thin spot phenomenon from occurring easily, and forming the electrode of a fine pattern precisely for improving performance.
