In an electric drive device, a motor housing includes an end face part opposite to an output part of a rotating shaft of a motor. An electronic control part is arranged at the end face part of the motor housing, and includes a control circuit part, a power supply circuit part, and a power conversion circuit part. The power conversion circuit part is mounted to a power conversion part heat dissipation region of the end face part of the motor housing. The power supply circuit part is mounted to a power supply part heat dissipation region of the end face part of the motor housing. A power conversion circuit part holder is attached to a portion of the end face part around the rotating shaft, and includes a resilient function member structured to press and hold the power conversion circuit part on the power conversion part heat dissipation region.
