Claims (1)

[Scope of utility model registration request] one capacitor unit having terminal electrodes formed on both end faces; a tape-shaped first dielectric film each having a substantially constant width and having an electrode film formed on one main face; a tape-shaped second dielectric film having approximately the same width as the first dielectric film and having an electrode film formed on one main surface; and another capacitor unit having the electrode film of a second dielectric film superimposed and wound on the surface thereof, and an insulating sheet being wound on the outer surface of the one capacitor unit, and an insulating sheet being wound in two directions. The other capacitor unit, which is formed into a flat shape by applying forces in opposite directions from each other, is curved so as to wrap around the one capacitor along the outer surface of the insulating sheet, and the outer surface is made of metal. It is surrounded by a short electrode tube, and the terminal electrode formed on one end surface of the another capacitor unit has the electrode film extending from one side of the first dielectric film to the other side with a certain margin. While the other capacitor unit is drawn out, a terminal electrode formed on the other end surface of the second capacitor unit has a side corresponding to the one side separated by a certain margin from the side corresponding to the other side of the first dielectric film. The electrode films of the above one and the other capacitor units are drawn out, and the terminal electrodes on each end face of the one and the other capacitor units are electrically connected to each other, while the terminal electrodes of the one and the other capacitor units are electrically connected to each other. A film capacitor characterized in that lead terminals are electrically connected to terminal electrodes on the other end surface.
