[Problem] To provide a power conversion device and a car control device capable of reducing the influence of heat generated in the devices. [Solving Means] A power conversion device according to an embodiment includes a converter unit including a plurality of semiconductor switching devices and configured to convert AC power to DC power, and an inverter unit disposed to be adjacent to the converter unit in a railroad car running direction and including a plurality of semiconductor switching devices, the inverter unit being configured to convert the DC power outputted from the converter unit to AC power. First radiation fins are attached to a surface of a first heat receiving plate opposite to a surface on which the semiconductor switching devices are attached, and second radiation fins are attached to a surface of a second heat receiving plate opposite to a surface on which the semiconductor switching devices are attached. The first radiation fins and the second radiation fins facing one another are attached to the first heat receiving plate and the second heat receiving plate so that recessed portions of the first radiation fins and recessed portions the second radiation fins are aligned with one another.
