Abstract
An object of the present invention is to provide a power conversion device capable of reducing an influence of electromagnetic noise propagating from a circuit body toward a drive circuit board.A power conversion device 100 of the present invention includes a circuit body 6 that converts a direct current into an alternating current, a drive circuit board 5 that drives the circuit body 6, a base member 4 provided between the circuit body 6 and the drive circuit board 5, and a case 1 that houses the circuit body 6 and the base member 4. The base member 4 includes a first flow channel forming portion 4A that forms a flow channel space 1C1 between the circuit body 6 and the base member 4, and a first extending portion 4B2 extending from the flow channel forming portion 4A and connected to an inner surface of the case 1.
