Abstract
Official abstract text for this publication.
A film capacitor includes a pair of mutually opposed dielectric films; and evaporated electrodes respectively provided on the pair of dielectric films. The evaporated electrode provided on one of the pair of dielectric films includes slits that are regions in which the evaporated electrode is not provided, a plurality of electrode regions defined by the slits, and at least one fuse portion that connects the electrode regions adjacent to each other. The one dielectric film, on which the evaporated electrode including the slits and the at least one fuse portion is provided, includes at least one through portion that extends through the one dielectric film, the at least one through portion being provided in at least one area corresponding to at least one of the slits adjacent to the at least one fuse portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A film capacitor comprising: a pair of mutually opposed dielectric films; and evaporated electrodes respectively provided on the pair of dielectric films, wherein the evaporated electrode provided on one of the pair of dielectric films includes slits that are regions in which the evaporated electrode is not provided, a plurality of electrode regions defined by the slits, and at least one fuse portion that connects the electrode regions adjacent to each other, and the one dielectric film, on which the evaporated electrode including the slits and the at least one fuse portion is provided, includes at least one through portion that extends through the one dielectric film in a thickness direction, the at least one through portion being provided in at least one area corresponding to at least one of the slits adjacent to the at least one fuse portion. 2. The film capacitor according to claim 1 , wherein each of the at least one through portion is constituted by a cut portion provided in the one dielectric film to extend along the corresponding slit.
