Abstract
A power conversion apparatus includes a capacitor and a heat dissipation member for cooling the capacitor. The capacitor and the heat dissipation member are pressed in an arranging direction in which the capacitor and the heat dissipation member are arranged. The capacitor includes a capacitor element which includes a dielectric body and a metal layer formed on a surface of the dielectric body, an electrode part connected to the metal layer and a bus bar connected to the electrode part. Part of the bus bar is interposed in the arranging direction between the heat dissipation member and the capacitor element.

7. A power conversion apparatus comprising:
-
a capacitor including; a capacitor element including; a dielectric body; and a metal layer formed on a surface of the dielectric body; an electrode part connected to the metal layer; and a bus bar connected to the electrode part; an electronic component electrically connected to the capacitor; a heat dissipation member for cooling the capacitor, the capacitor and the heat dissipation member being pressed in an arranging direction in which the capacitor and the heat dissipation member are arranged, part of the bus bar being interposed in the arranging direction between the heat dissipation member and the capacitor element, and the heat dissipation member including a cooling tube formed with a flow channel through which coolant flows; a stacked body including the capacitor, the electronic component, and the cooling tube stacked on one another in the arranging direction; and a case that houses the stacked body in a state of being pressed in the arranging direction such that the cooling tube is elastically deformed and held between wall parts of the case, the cooling tube and the capacitor being pressed in the arranging direction by a resilient return force of the cooling tube being deformed.
