PROBLEM TO BE SOLVED: To provide a metallized film capacitor capable of suppressing heat generation in a fuse while securing an excellent security function and also reducing ESR (equivalent serial resistance). SOLUTION: By providing a division margin 6 which extends in the width direction of a dielectric film and whose one end is positioned at the boundary of a connection part 5 and an effective electrode and other end is connected to an insulation margin 4, the effective electrode is divided at prescribed intervals in the longitudinal direction. The divided effective electrodes are divided into a connection part side division electrode 11 and an insulation margin side division electrode 12 at the almost center of the width direction. Both the division electrodes 11 and 12 are connected by the fuse 9. Also, for the connection side division electrode 11, the whole width of the end on the side of the connection part 5 is connected to the connection part 5 as it is. The film thickness of the vapor deposition electrode of the connection part 5 is made thicker than the film thickness of the vapor deposition electrode of the effective electrode. The fuse 9 of a first electrode film 3A and the fuse 9 of a second electrode film 3B are disposed so as not to be overlapped in the thickness direction of the dielectric film.
