ELECTRIC COMPRESSOR

To provide an electric compressor that can improve cooling performance of a switching element.SOLUTION: A switching element 70 comprises a conductive member 71, and a resin member 72 having a rectangular parallelepiped shape. The resin member 72 comprises: a first end surface 72a that is an end surface in a longitudinal direction, and from which a portion of the conductive member 71 protrudes; a second end surface 72b that is an end surface on a side opposite to the first end surface 72a; and a first side surface 72c connecting the first end surface 72a and the second end surface 72b. The conductive member 71 comprises a heat generation part 73a exposed in the first side surface 72c. The switching element 70 is arranged in an inverter housing chamber S1 in such a manner that the longitudinal direction of the resin member 72 extends in an axial direction of a rotating shaft. A heat dissipation member 80 made of metal is arranged between the switching element 70 and a partition wall 22. The heat dissipation member 80 comprises a first heat dissipation part 81 arranged between the heat generation part 73a and the partition wall 22, and a second heat dissipation part 82 continuous with the first heat dissipation part 81, and arranged between the second end surface 72b and the partition wall 22.SELECTED DRAWING: Figure 4 【課題】スイッチング素子の冷却性能を向上できる電動圧縮機を提供する。【解決手段】スイッチング素子７０は、導電部材７１と直方体状の樹脂部材７２とを有する。樹脂部材７２は、長手方向の端面であるとともに導電部材７１の一部が突出する第１端面７２ａと、第１端面７２ａとは反対側の端面である第２端面７２ｂと、第１端面７２ａと第２端面７２ｂとを繋ぐ第１側面７２ｃとを有する。導電部材７１は、第１側面７２ｃにおいて露出する発熱部７３ａを有する。スイッチング素子７０は、樹脂部材７２の長手方向が回転軸の軸方向に延びるようにインバータ収容室Ｓ１に配置される。スイッチング素子７０と区画壁２２との間には、金属製の放熱部材８０が配置される。放熱部材８０は、発熱部７３ａと区画壁２２との間に配置される第１放熱部８１と、第１放熱部８１と連続するとともに第２端面７２ｂと区画壁２２との間に配置される第２放熱部８２とを有する。【選択図】図４
