PURPOSE: An electric radiator is provided to enhance heat exchange efficiency of an electric heater by a heat radiating member integrally attached to make heat conduction by heat exchange plates arranged in a spiral shape at regular intervals. CONSTITUTION: An electric radiator comprises an electric heater(32), a heat radiating member(30), a hollow member(42) and a radiation member(40). For the heat radiating member, heat exchange plates(340) are spirally installed on the outer circumferential surface of the heater in a longitudinal direction. The heat radiating member is formed to make heat conduction. The hollow member comprises the heat radiating member. For the radiation member, heat radiating plates(44) are installed on the outer circumferential surface of the hollow member. The radiation member forms on the leading end of the heat radiating plate a deflected radiation piece(45), which is bent in one direction.
