Abstract: A power conversion device according to an embodiment includes a converter unit, and an inverter unit disposed to be adjacent to the converter unit in a railroad car running direction, 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.
