Abstract
A film capacitor according to the present disclosure includes a first film and a second film wound in a stacked state and a first deposition electrode and a second deposition electrode that are formed by metal deposition. The second deposition electrode includes widthwise slit portions, the widthwise slit portions crossing the second deposition electrode in its widthwise direction, split electrodes split by the widthwise slit portions, and a longitudinal slit portion extending in a longitudinal direction of the second deposition electrode in an ineffective electrode region shifted from an effective electrode region in the widthwise direction of the second deposition electrode. Each split electrode includes a first fuse portion bridging over a longitudinal slit portion and a second fuse portion that bridges over a widthwise slit portion and can be fused with a current smaller than a current for the first fuse portion.
