To provide an electric drive apparatus and an electric power steering apparatus capable of efficiently radiating heat generated by energization of a choke coil while reducing axial size.SOLUTION: An electric drive apparatus includes a motor, an electronic control section including a circuit board, and a heat sink. A connector is provided on a radial side of a shaft of the heat sink. The heat sink has a recess into which a choke coil is inserted on an anti-load side, and has a housing section projecting toward the connector.SELECTED DRAWING: Figure 9

    【課題】軸方向の大きさが小さくしつつ、チョークコイルが通電により発生する熱をより効率的に放熱可能な電動駆動装置及び電動パワーステアリング装置を提供する。【解決手段】電動駆動装置は、モータと、回路基板を含む電子制御装置と、ヒートシンクと、を含む。コネクタは、ヒートシンクのシャフトの径方向の側方に設けられる。ヒートシンクは、反負荷側にチョークコイルが挿入される凹部を有し、かつコネクタ側に突出する収容部を有する。【選択図】図9
