METALLIZED FILM CAPACITOR AND MANUFACTURE THEREOF

摘要

PURPOSE:To obtain a metallized film capacitor which enhances a mechanical strength and which does not cause a stress even when a heat treatment is executed by a method wherein a metallized film is used as an insulating part which does not contribute to an electrostatic capacity and the metallized film has a belt-shaped margin which is parallel to an electrode direction. CONSTITUTION:A margin is executed on a one-face metallized film at each of layers A, C which do not contribute to a capacity and a layer B which contributes to the capacity. The layer B generates an electrostatic capacity by alternately laminating two layers whose positions of margins are different with reference to a right electrode direction and a left electrode direction. In the layers A and C, individual layers whose positions of margins are equal with reference to the right electrode direction and the left electrode direction are laminated to form a reinforcement film layer. Consequently, a mechanical connection strength between an electrode end-part and a sprayed metal electrode of the layer A or C can be enhanced; the individual layers are formed of the same metallized film; and a stress is not caused by a heat treatment.
