The rear tab includes a rear held portion adjacent to the base portion and a rear male terminal portion housed in the rear insertion recess portion. The front tab includes a front held portion adjacent to the extension end of the extension portion and a front male terminal portion housed in the front insertion recess portion. The busbar holding portion includes a first holding portion that holds the rear held portion of the rear tab, a second holding portion that holds the front held portion of the front tab, and a third holding portion that holds the extension portion.
