Zusammenfassung:To provide a technique capable of efficiently performing an appearance inspection on an external connection part in a square pole shape protruding upward from a sidewall part of a case in a power module.SOLUTION: A power module 202 comprises: a conductor layer 13 provided on an insulation substrate 11; power semiconductor elements 21 and 22 disposed on the conductor layer 13; a case 51 enclosing the insulation substrate 11, the conductor layer 13 and the power semiconductor elements 21 and 22; a plurality of signal terminals 62 disposed along one side of a sidewall part 511 of the case 51; and a sealing resin 7 filling the inside of the case 51 and covering the power semiconductor elements 21 and 22. Each signal terminal 62 includes: an internal connection part 622 protruding to an inner peripheral side of the sidewall part 511 and electrically connected with the power semiconductor element 22; and an external connection part 621 in a square pole shape protruding upward from the sidewall part 511. Each signal terminal 62 is disposed while being rotated in a range from 5° or more to 40° or less with respect to a width direction of the sidewall part 511.SELECTED DRAWING: Figure 1 【課題】パワーモジュールにおいて、ケースの側壁部から上方に突出する四角柱状の外部接続部に対する外観検査を効率よく行うことが可能な技術を提供することを目的とする。【解決手段】パワーモジュール202は、絶縁基板11上に設けられた導体層13と、導体層13上に配置されたパワー半導体素子21,22と、絶縁基板11、導体層13およびパワー半導体素子21,22を囲繞するケース51と、ケース51の側壁部511の一辺に沿って配置された複数の信号端子62と、ケース51内に充填され、パワー半導体素子21,22を覆う封止樹脂7とを備える。各信号端子62は、側壁部511の内周側に突出しパワー半導体素子22と電気的に接続される内部接続部622と、側壁部511から上方に突出する四角柱状の外部接続部621とを有する。各信号端子62は、側壁部511の幅方向に対して、5°以上40°以下の範囲内で回転した状態で配置される。【選択図】図1
