Claims (1)

[Scope of utility model registration request] A tape-shaped first dielectric film each having a substantially constant width and having an electrode film formed on one main surface; and a tape-shaped second dielectric film having an electrode film formed on its surface, and the electrode film of the second dielectric film is superimposed on another main surface of the first dielectric film. A first capacitor unit is wound, and an insulating sheet is wrapped around the outer surface of the first capacitor unit, each having a substantially constant width, and an electrode film formed on one main surface. a tape-shaped third dielectric film having a width approximately equal to that of the third dielectric film, and a tape-shaped fourth dielectric film having an electrode film formed on one main surface; A second capacitor unit is formed by overlapping the electrode film of a fourth dielectric film on another main surface of the third dielectric film and wrapping the electrode film around the outer surface of the insulating sheet. and a terminal electrode formed on one end surface of the first and second capacitor units, the electrode extending from one side of the first and third dielectric films to the other side with a certain margin. While the film is pulled out, a certain margin is left between the terminal electrodes formed on the other end surfaces of the first and second capacitor units from the sides corresponding to the other sides of the first and third dielectric films. The electrode film is drawn out to a side corresponding to the one side, and the terminal electrodes on each end face of the first and second capacitor units are electrically connected to each other, while the first and second capacitor units are electrically connected to each other. A capacitor characterized in that two or more lead terminals are electrically connected to each terminal electrode on the other end surface of the second capacitor unit.
