Claim:
1. A power conversion apparatus, comprising: an electric circuit element configured to operate for power conversion, the electric circuit element generating heat during operation; a cooler attached to the electric circuit element and configured to cool the electric circuit element by releasing into the air the heat generated by the electric circuit element in operation; a connection frame including a plate-like frame portion to which the cooler is attached; a capacitor that is a structural member disposed in a direction perpendicular to the frame portion and including a capacitor element electrically connected to the electric circuit element, the capacitor including a first support surface and a second support surface that are external surfaces facing in opposite directions from each other and parallel to the direction perpendicular to the frame portion; a first frame including an end portion fixed to the connection frame and a first attachment surface fixed to the first support surface; and a second frame including an end portion fixed to the connection frame and a second attachment surface opposed to the first attachment surface and fixed to the second support surface, wherein the direction perpendicular to the frame portion is horizontal, wherein the first support surface is one side surface of the capacitor and the second support surface is another side surface of the capacitor, and wherein the first frame and the second frame do not cover a top surface of the capacitor.
