The present invention provides an electric pump, the electric pump comprising: a motor unit which includes a shaft, a rotor coupled to the shaft, and a stator disposed outside the rotor; a pump unit which includes a first rotor including a first lobe coupled to the motor unit and having a plurality of gear teeth, and a second rotor disposed outside the first rotor and including a second lobe; and a second cover including a second surface on which the pump unit is disposed, wherein the second surface has a second suction port and a second discharge port disposed thereon, and the second suction port provided on the second surface includes a third protrusion protruding to the inside of the second suction port. The angle formed by a first line connecting the center of the first rotor and the center of the second rotor, and a second line connecting the center of the first rotor and a distal end of the third protrusion is inversely proportional to the number of gear teeth of the first lobe.
