To provide an electric driving device and an electric power steering device that have a smaller size in the axial direction and suppress stress on a circuit board due to electrical connection between a motor and the circuit board if a terminal block is provided. 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 first heat sink, a second heat sink, and a terminal block. The second heat sink sandwiches the first circuit board between it and the first heat sink. The terminal block is fixed to the side surface of the second heat sink and electrically connects motor coil wiring to the first circuit board.
