An electric drive device includes a housing with a motor-housing-side annular groove portion formed on an outer peripheral surface of an end surface portion of the housing, on an opposite side to an output portion of a rotation shaft of an electric motor section. The groove portion is formed by an annular groove retreating inward in the radial direction orthogonal to the axial line of the housing. A metal-cover-side distal end portion is formed at the opening end of a metal cover covering an electronic control unit that controls the electric motor section, and faces the groove from the outer side. A space between the groove portion and the distal end portion is filled with a liquid sealant, and an annular inclined surface is inclined so it is widened outward in the radial direction of the metal cover is formed on the inner peripheral surface of the groove portion.
