Power conversion device

A power conversion device comprising:

• a power module that performs switching operation;
• a smoothing capacitor that smooths a voltage ripple caused by the switching operation;
• a circuit board that controls driving of the power module;
• a housing that accommodates the power module and the smoothing capacitor;
• a first fixing member for fixing the power module to the housing;
• and
• a second fixing member for fixing the smoothing capacitor to the housing, wherein
• the circuit board straddles between the power module and the smoothing capacitor, and is fixed by the first fixing member and the second fixing member, and
• at least one of the first fixing member and the second fixing member is made of an electric conductive material.
