Abstract
An electric pump device includes a motor having a rotor and a stator portions, a pump portion and a housing. The stator portion has a stator core, and coils each having a winding portion and a crossover portion. The housing has a housing body portion having a tubular shape and extending in the axial direction, and a flange portion expanding radially outward from the outer peripheral surface of the housing body portion. The flange portion has an end surface that faces toward one side in the axial direction and is disposed in the axial direction between a first and a second virtual plane. The first and the second virtual planes pass through parts of the stator core, the winding portion, and the crossover portion located respectively closest to one and the other sides in the axial direction and expanding in a direction perpendicular to a central axis.
