High-voltage feedthrough capacitor

A high-voltage feedthrough capacitor comprising:

• a capacitor including an element body in which a through hole extending in a first direction is formed, and a first electrode and a second electrode disposed facing each other on the element body;
• a feedthrough conductor inserted through the through hole and electrically connected to the first electrode;
• a grounding fitting electrically connected to the second electrode;
• and
• a first case and a second case having a tubular shape and surrounding the feedthrough conductor,
• wherein the element body includes:
• a first end face and a second end face facing each other in the first direction;
• a first protruding part in which the through hole opens, the first protruding part being provided on the first end face;
• and
• a second protruding part in which the through hole opens, the second protruding part being provided on the second end face,
• wherein the first case is attached to the first protruding part, and
• wherein the second case is attached to the second protruding part.
