<p>PROBLEM TO BE SOLVED: To obtain an electric power conversion device which inhibits adverse effect of heat from a heating component on other components and improves the flexibility of the arrangement of the heating component while inhibiting the deterioration of the cooling efficiency of the heating component.SOLUTION: An electric power conversion device body 2 includes: a printed circuit board 11; a heating component 13 provided on the printed circuit board 11; a metal cover 14 which is attached to the printed circuit board 11 while covering the heating component 13; and a gap heat transmission material 15 which fills at least a part of a gap between the heating component 13 and the cover 14 while deforming so as to fit with shapes of the heating component 13 and the cover 14 and transmits heat from the heating component 13 to the cover 14. A housing (a support member) 3 supports the electric power conversion device body 2 while being connected with the cover 14 so as to transmit heat to the cover 14 and radiates the heat to the exterior.</p> |
