ELECTRIC POWER CONVERSION DEVICE AND MANUFACTURING METHOD OF ELECTRIC POWER CONVERSION DEVICE

To provide a manufacturing method of an electric power conversion device, which improves heat radiation ability in the electric power conversion device using a power semiconductor element, and does not require a metal molding for a press processing.SOLUTION: An electric power conversion device 100 comprises an insulation substrate 20, a heat discharge member 40, a resin spacer 50 and a resin member 60. A power semiconductor electrode 10 is provided with one main surface of the insulation substrate 20. The heat discharge member 40 is opposite to the other main surface of the insulation substrate 20. The insulation spacer 50 has an insulation property, and is positioned between the other main surface of the insulation substrate 20 and the heat discharge member 40. The resin member 60 has the insulation property, and embeds a residual part between the other main surface of the insulation substrate 20 and the heat discharge member 40.SELECTED DRAWING: Figure 1 【課題】パワー半導体素子を用いた電力変換装置における放熱能力を向上させ、また、プレス加工用の金型が不要である電力変換装置の製造方法を提供する。【解決手段】電力変換装置１００は、絶縁基板２０、放熱部材４０、樹脂スペーサ５０及び樹脂部材６０を備える。絶縁基板２０の一方主面には、パワー半導体素子１０が取り付けられる。放熱部材４０は、絶縁基板２０の他方主面と対向している。樹脂スペーサ５０は、絶縁性を有し、絶縁基板２０の他方主面及び放熱部材４０の間に位置する。樹脂部材６０は、絶縁性を有し、絶縁基板２０の他方主面及び放熱部材４０の間の残余の部分を埋めている。【選択図】図１
