PROBLEM TO BE SOLVED: To provide a power conversion device which, even if it is an electromagnetic induction apparatus having a large variation in size, can stabilize thermal resistance between the electromagnetic induction apparatus and a cooling part without being influenced by variation and also can reduce the thermal resistance.SOLUTION: There is disclosed a power conversion device according to the present invention which includes: a printed wiring board 4; a reactor 1 electrically connected to this printed wiring board 4; a chiller 5 which is provided opposite to the printed wiring board 4 via this reactor 1 and cools the reactor 1; and a case 2 which houses the reactor 1 therein, whose opening is located on the printed wiring board 4 side, whose end surface of a side surface is connected to the printed wiring board 4, and which has heat conductivity and electrical insulation properties, having a U-shaped cross section. The reactor 1 in the case 2 has a void on the printed wiring board 4 side and abuts on a bottom surface 2a of the case 2. |
