Abstract
The present disclosure relates to a metal case capacitor that includes: a capacitor module (10) including a capacitor device, a first busbar (1) electrically connected with a thermally-sprayed surface of the capacitor device and having a first lead terminal (1a) on an exposed side, a second busbar (2) electrically connected with the other thermally-sprayed surface of the capacitor device and having a second lead terminal (2a) on an exposed side, and an insulating sheet disposed between the first busbar (1) and the second busbar (2); a metallic external case (20) having a space; a plastic insulating member positioned between the capacitor module (10) and the metallic external case (20) and insulating the capacitor module (10) and the metallic external case (20) from each other; and a filler permeating in a gel or liquid state into a space between the capacitor module (10) and the metallic external case (20).
