Capacitor and manufacturing method thereof

A capacitor comprising:

• a capacitor element;
• a protection film;
• a first bus bar;
• a second bus bar;
• and
• a seal portion covering the capacitor element that is covered by the protection film, wherein:
• the capacitor element includes:
• an element body having a first end-face, a second end-face on an opposite side of the first end-face, and an outer peripheral surface between the first end-face and the second end-face,
• a first end-face electrode disposed on the first end-face, and
• a second end-face electrode disposed on the second end-face,
• the first bus bar is connected to the first end-face electrode,
• the second bus bar connected to the second end-face electrode,
• the protection film includes a first protection portion covering a surface of the first end-face electrode that faces the first end-face, a second protection portion covering a surface of the second end-face electrode that faces the second end-face, and a third protection portion connecting the first protection portion and the second protection portion and covering the outer peripheral surface, and
• the seal portion is in contact with a part of the first end-face electrode that is not covered by the protection film and a part of the second end-face electrode that is not covered by the protection film.
