PURPOSE: To provide a metallized film capacitor which is free from danger of ignition or explosion and is easy of manufacture with simple structure.
CONSTITUTION: In a metallized film capacitor 64 which has a rolled metallized film member 30 which is made by putting a pair of metallized films 14 and 20, where the surfaces of dielectric films 10 and 16 are covered, respectively, with electrode metals 12 and 18, on top of the other, and rolling these, a safety belt 34, where first copper foil 40 connected to a first outer electrode 52 and a second copper foil 44 connected to a second outer electrode 56 are counterposed with an insulating film 36, which fuses at a specified temperature or more, between, is wound on the periphery 46 of the rolled metallized film member 30.
