To reduce the manufacturing cost of a power conversion device in which a power conversion circuit and a reactor are mounted on the same substrate.SOLUTION: A power conversion device 100 includes a converter circuit 110 having a power semiconductor, an inverter circuit 130 having a power semiconductor, a reactor 121, and a printed circuit board 71. The reactor 121 has a core 201 and winding 202. The converter circuit 110, the inverter circuit 130, and the reactor 121 are mounted on the same printed circuit board 71. Of the winding 202 of the reactor 121, a wire wound around the core 201 is made of a material whose electrical resistivity (Ω m) at 20°C is higher than that of copper.SELECTED DRAWING: Figure 4 【課題】電力変換回路とリアクトルとを同一の基板に実装する電力変換装置の製造コストを抑える。【解決手段】電力変換装置１００は、パワー半導体を有するコンバータ回路１１０及びインバータ回路１３０と、リアクトル１２１と、プリント基板７１とを備えている。リアクトル１２１は、コア２０１と巻線２０２とを有する。コンバータ回路１１０及びインバータ回路１３０とリアクトル１２１とは、同一のプリント基板７１に実装されている。リアクトル１２１の巻線２０２のうち、コア２０１に巻きつけられる線は、２０℃における電気抵抗率（Ω・ｍ）が銅よりも高い物質から成る線である。【選択図】図４
