A power conversion device according to an embodiment comprises a semiconductor element, an air receiver, an air guide, an airflow straightener, and a flange. Assuming that the assumed travel direction of a vehicle is a first direction, the direction of gravity is a second direction, and the direction perpendicular to the first direction and the second direction is a third direction, the air guide is disposed to face the air receiver in the third direction, and includes two ends in the first direction. The end closer to the center of the air receiver is defined as a first end and the end on the opposite side from the first end is defined as a second end. The airflow straightener extends from the first end of the air guide along the first direction and away from the second end. The flange extends from the second end of the air guide and away from the air receiver.
