Zusammenfassung:	A drive device includes a motor and a control unit that are configured integrally. A motor frame is disposed at an end portion of the motor close to the control unit. A cover includes a top plate portion facing the motor frame and an outer cylinder portion extending from an outer edge of the top plate portion toward the motor frame. Two or more boards are arranged in multiple stages between the motor frame and the top plate portion, and electronic components constituting the control unit are mounted on the boards. The boards include a first board closest to the motor frame and a second board arranged in a second stage. An inter-board connection component electrically connects adjacent boards. Composite fastening members fasten the first board to the motor frame on a same axis as fastening the second board to the motor frame.
