Abstract
A stacked film capacitor device has less capacitance loss. The film capacitor device includes a film stack with metal layers including adjacent metal layers in 180° opposite orientations in a direction in which the metal layers extend continuously, and a first metal electrode and a second metal electrode on a pair of end faces of the film stack. At least one of a pair of end faces of the film stack in y-direction includes a recess continuously extending in a stacking direction and separating the film stack from the first metal electrode. The recess electrically insulates the metal layers serving as internal electrodes from a metal-sprayed electrode serving as an external electrode.
