To provide an electrically-driven driver that can be downsized and can improve heat dissipation efficiency.SOLUTION: An electrically-driven driver comprises: a motor comprising a shaft that protrudes from a motor case and rotates; and a controller for controlling the motor. The controller comprises: a heat sink that comprises a partition wall having a hole penetrating in an axial direction of the shaft and is coupled to the motor case; a control board disposed on one side of the partition wall; and a power board disposed on the other side of the partition wall; and a connector. The connector comprises a plug disposed on one of the control board and the power board and a receptacle disposed on the other of the control board and the power board and penetrates the hole.SELECTED DRAWING: Figure 3 【課題】小型化でき且つ放熱効率を向上させることができる電動駆動装置を提供すること。【解決手段】電動駆動装置は、モータケースから突出し回転するシャフトを備えるモータと、モータを制御する制御装置と、を備える。制御装置は、シャフトの軸方向に貫通する孔を有する隔壁を備え且つモータケースと連結されるヒートシンクと、隔壁の一方側に配置される制御基板と、隔壁の他方側に配置されるパワー基板と、コネクタと、を備える。コネクタは、制御基板及びパワー基板の一方に配置されるプラグ、及び制御基板及びパワー基板の他方に配置されるレセプタクルを備え、且つ孔を貫通する。【選択図】図３
