Claim 4:
5. A metal case capacitor comprising:
a capacitor module including a capacitor device formed by winding a dielectric film and having thermally-sprayed surfaces on both sides, a first busbar electrically connected with at least one of the thermally-sprayed surfaces of the capacitor device and having a first lead terminal on an exposed side, a second busbar electrically connected with the other thermally-sprayed surface of the capacitor device and having a second lead terminal on an exposed side, and an insulating sheet disposed between the first busbar and the second busbar to insulate an overlap region;
a metallic external case having a space, in which the capacitor module is accommodated;
a plastic insulating member positioned between the capacitor module and the metallic external case and insulating the capacitor module and the metallic external case from each other; and
a filler permeating in a gel or liquid state into a space between the capacitor module and the metallic external case and then cured therein,
wherein the plastic insulation housing is a plastic housing having a plurality of separate openings and forms a 3D space and insulation gap formation members positioned on a plurality of planes forming the outline of the space are disposed in a mesh type.
