    摘要: A film condenser formed of a solderable metal foil composed on one member 1 selected from the group consisting of copper, tin, and aluminum having a heat resistant plastic film 2 coated on one surface and a vapor-deposited metal film 3 on the surface of the heat resistant plastic film facing away from the metal foil. Two lead wires each having a part bent in the shape of a V or u with the open end facing laterally of the length of the wire and having a size to prevent solder in a molten state from flowing out of the bent part during soldering due to the surface tension of the molten solder are soldered to the other surface of the metal foil and to the surface of the metal film facing away from the plastic film.
