Abstract: A film capacitor includes a capacitor element that includes an element body formed of a winding of or a laminate of metallized films and a P pole electrode and an N pole electrode that are respectively formed on opposite end faces of the element body. The film capacitor also includes a P electrode bus bar and an N electrode bus bar that are respectively connected to the P pole electrode and the N pole electrode, and an electrically conductive covering that covers a peripheral surface of the capacitor element with the covering spaced away from at least one of the P pole electrode or the N pole electrode.

Abstract: A capacitor includes a capacitor element and a protection film. The capacitor element includes a first end-face electrode, a second end-face electrode, and an outer peripheral surface. The second end-face electrode exists on the opposite side of the first end-face electrode. The outer peripheral surface exists between the first end-face electrode and the second end-face electrode. The protection film includes a first protection portion, a second protection portion, and a third protection portion. The first protection portion protects the periphery of the first end-face electrode. The second protection portion protects the periphery of the second end-face electrode. The third protection portion is connected to the first and second protection portions and protects the outer peripheral surface.
