An electric motor includes: a case; a stator including a stator core disposed inside the case and a stator coil wound around the stator core; a rotor including a rotating shaft and being configured to rotate with respect to the stator; and an oil spraying part that is configured to store oil in a lower part of the case, that includes an oil passage configured to guide the oil to an upper area of the case and an oil pump for pumping the oil, and that is configured to spray the oil to an inner heating part of the case. Accordingly, the oil can suppress occurrence of short-circuiting of an electric circuit and rapidly cool a heating part.
