Provided is a power conversion device with which it is possible to achieve size reduction and improve reliability by reducing the number of components of a system as a whole. The power conversion device (100) comprises a semiconductor module (110) of a half-bridge configuration in which two semiconductor elements are arranged in series. The semiconductor module (110) has a substantially cuboidal shape and has, along a longitudinal direction of the cuboid, a positive pole terminal, a negative pole terminal, and terminals for inputting or outputting alternating current or for specific purposes, forming a single phase of the power conversion device (100). In the vertical direction corresponding to a widthwise direction of the cuboid, a plurality of the semiconductor modules (110) are arranged vertically, forming a plurality of phases of the power conversion device (100). The semiconductor modules (110) of the plurality of phases are installed in contact with a cooling unit (150), and one or more capacitors (120) are disposed so as to face the cooling unit (150) across the semiconductor modules (110) of the plurality of phases.
