Abstract
An object of the present invention is to ensure the reliability of a capacitor element by appropriately securing a heat path around the capacitor element. A power converter according to the present invention includes: a power semiconductor circuit unit that converts DC power into AC power; a capacitor element that smooths the DC power; a DC-side bus bar that transmits the DC power; a capacitor terminal that is connected to an electrode surface of the capacitor element and to the DC-side bus bar; and a case that forms a capacitor housing portion for housing the capacitor element, in which the DC-side bus bar has: a power supply-side terminal; a main body portion that is arranged at a position facing a bottom of the capacitor housing portion with the capacitor element interposed therebetween; and an extending member that is formed between the case and the capacitor element and formed from the main body portion toward the bottom of the capacitor housing portion, and that does not contact the electrode surface.
