Zusammenfassung:	To provide a power conversion device the cooling performance of which can be improved.SOLUTION: A power conversion device 1 for converting DC voltage to AC voltage, includes a first substrate 100 on which a power conversion circuit is mounted, a second substrate 200 on which a driving circuit for driving the power conversion circuit is mounted, a shielding board 300 disposed between the first substrate 100 and the second substrate 200, and a sensor module 400. The first substrate 100 is a metal substrate. A plurality of power conversion semiconductor elements of the power conversion circuit are mounted on the upper surface of the first substrate 100.SELECTED DRAWING: Figure 1B 【課題】冷却性能を向上させることができる電力変換装置を提供する。【解決手段】直流電圧を交流電圧に変換する電力変換装置１は、電力変換回路が搭載された第一基板１００と、電力変換回路を駆動する駆動回路が搭載された第二基板２００と、第一基板１００と第二基板２００との間に配設されたシールド板３００と、センサモジュール４００と、を備える。第一基板１００は金属基板であり、第一基板１００の上面には、電力変換回路の複数の電力変換用半導体素子が実装される。【選択図】図１Ｂ
