Capacitor

A capacitor comprising:

• a capacitor element unit;
• and
• a case that is made of a metal and houses the capacitor element unit, the capacitor element unit including:
• a capacitor element;
• a first electrode disposed on one of both end faces of the capacitor element;
• a second electrode disposed on another one of the both end faces of the capacitor element;
• a first bus bar connected to the first electrode, the first bus bar including a first region;
• a second bus bar connected to the second electrode, the second bus bar including a second region facing the first region;
• and
• a first insulating member that has an insulation property and is disposed between the first region and the second region, wherein:
• the first insulating member includes a first mounting portion, and
• the case includes a second mounting portion to which the first mounting portion is attached so that the capacitor element unit is located at a predetermined position with respect to the case while the first bus bar and the second bus bar are not in contact with the case.
