An electric drive device includes: a motor housing for housing an electric motor, wherein the motor housing includes an end face part opposite to an output part of a rotating shaft of the electric motor; and an electronic control part arranged at the end face part. The electronic control part includes a control circuit part, a power supply circuit part, and a power conversion circuit part, which are covered by a metal cover, wherein the metal cover is fixed water-tightly to the end face part. The end face part includes a power conversion heat dissipation region and a power supply heat dissipation region. Each of the control circuit part and the power supply circuit part is contained on a circuit board, wherein the circuit board is placed along a plane perpendicular to the rotating shaft, and layered with each other in an axial direction of the rotating shaft.
