Abstract: A capacitor includes a plurality of capacitor element units, a case housing the plurality of capacitor element units, a filling resin in the case, and an external connection bus bar. Each of the plurality of capacitor element units includes a capacitor element and a relay bus bar. The capacitor element has two end surfaces and a peripheral surface, and an electrode disposed on at least one of the two end surfaces. The relay bus bar includes an electrode connecting part connected to the electrode and a connection terminal disposed to face the peripheral surface. The external connection bus bar includes an internal connection terminal connected to the connection terminal and an external connection terminal being exposed from the filling resin and configured to connect to an external terminal. The plurality of capacitor element units are arrayed in the case along a first direction parallel to a bottom surface of the case.
