    Abstract: To provide an electric driving device and an electric power steering device with a smaller area of power supply wiring in a circuit board and higher reliability of the circuit board. An electric driving device includes a motor and an electronic control unit that controls rotation of the motor. The electronic control unit includes a first circuit board, a second circuit board, a power supply wiring module, and a heat sink. The first circuit board is provided with a transistor that outputs an electric current to excite a motor coil. The second circuit board includes a control circuit that controls an electric current supplied to the transistor. The power supply wiring module is configured by molding, with resin, a choke coil for noise removal, a capacitor, and wiring that supplies electric power to at least one of the first circuit board and the second circuit board. The heat sink is sandwiched between the power supply wiring module and the second circuit board.
