1. A busbar structure for use in a capacitor, comprising:
a capacitor element
a first busbar and a second busbar disposed in a pair and each having a plate-like shape, the first busbar and the second busbar having different polarities and respectively comprising first and second plate portions that are disposed against and in parallel to each other, and
an insulating plate held between the opposing plate portions,
the insulating plate comprising a swelling that protrudes in a first direction that is a direction from the first plate portion toward the second plate portion, the swelling being integral with the insulating plate,
the first plate portion comprising a first fitting part that protrudes in the first direction, the first fitting part being integral with the first plate portion and allowed to fit onto one surface side of the swelling of the insulating plate in the first direction,
the second plate portion comprising a second fitting part that protrudes in the first direction, the second fitting part being integral with the second plate portion and allowed to fit onto another surface side of the swelling of the insulating plate in a second direction opposite to the first direction,
wherein
the swelling of the insulating plate comprises a tubular portion,
an outer circumferential surface of the first fitting part of the first plate portion is allowed to fit onto an inner circumferential surface of the tubular portion, and
an inner circumferential surface of the second fitting part of the second plate portion is allowed to fit onto an outer circumferential surface of the tubular portion.
