To provide an electric driving device and an electric power steering device which enable a power source wiring module to be easily assembled on a lid body, and prevent the power source wiring module from erroneously touching a connector.SOLUTION: An electric driving device includes a motor, and an electronic control device for controlling rotation of the motor. The electric control device includes a second housing, a metal lid body covering the second housing, a connector having a power source input terminal penetrating through the lid body, a lead frame wiring which has one end connected to the power source input terminal and supplies power to a first circuit board and a second circuit board, and a power source wiring module where a first power source terminal connected to the first circuit board, and a second power source terminal connected to the second circuit board are molded with a resin. In the power source wiring module, a plurality of first positioning projections project to the lid body side, and the first positioning projections are inserted into the positioning hole of the lid body.SELECTED DRAWING: Figure 12 【課題】蓋体に電源配線モジュールを組み付けしやすくなり、誤って電源配線モジュールがコネクタに接触しにくくなる、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、モータの回転を制御する電子制御装置とを備える。電子制御装置は、第２ハウジングと、第２ハウジングを覆う金属製の蓋体と、蓋体を貫通する電源入力端子を有するコネクタと、一端が電源入力端子に接続され、第１回路基板及び第２回路基板に電力を供給するリードフレーム配線と、第１回路基板へ接続する第１電源端子と、第２回路基板へ接続する第２電源端子とが樹脂でモールドされた電源配線モジュールと、を含む。電源配線モジュールは、複数の第１位置決め凸部が蓋体側に突出し、第１位置決め凸部が蓋体の位置決め穴に挿入されている。【選択図】図１２
