PROBLEM TO BE SOLVED: To provide a waste heat recovery system for an electric vehicle utilizing the waste heat of a propulsion device to perform heating by reduced electric power. SOLUTION: The waste heat recovery system uses heat generated in the propulsion device mounted to the electric vehicle 10 as a heat source of a heating device of the electric vehicle 10. The heat recovery system comprises: a radiator 23 absorbing the heat generated in the motor 21; a cooling circuit 2 having a bypass passage 25 bypassing an inlet passage and an outlet passage of the radiator 23; and a heating circuit 3 having a hot water producing device 31 heating a refrigerant and a heater core 32 supplying hot air in a vehicle compartment by using the refrigerant as the heat source. The cooling circuit 2 is connected by the heating circuit 3 with a four-directional valve 42 switching connection and separation between the cooling circuit 2 and the heating circuit 3.
