To provide an electric driving device and an electric power steering device that reliably transmit control signals and enhance heat dissipation of a first circuit board and a second 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 second housing, a lid, and an inter-board connector. The second circuit board includes a control circuit that controls an electric current supplied to a transistor of the first circuit board. The second housing accommodates the second circuit board and has a first through hole passing therethrough in the axial direction. The lid covers the second housing. The inter-board connector connects the second circuit board disposed on the anti-load side of the second housing to the first circuit board disposed on the load side of the second housing. The inter-board connector is disposed in the first through hole.
