A cooling performance of a power conversion device mounted in a rail vehicle is improved. A power conversion device for railway vehicle includes a plurality of power semiconductor elements and a heat-receiving member. The power conversion device has a surface on one side of the heat-receiving member on which the plurality of power semiconductor elements are mounted. The power conversion device has a configuration in which the heat-receiving member is installed in a lower portion of a vehicle body and in a horizontal direction, the power semiconductor elements are disposed on an upper side of the heat-receiving member, the heat-receiving member has a surface on an opposite side on which a heat dissipation unit made of a self-excited oscillation heat pipe is installed, and a wind generated by traveling of the vehicle is taken into the heat-receiving member.
