PURPOSE:To expetite atomization of fuel by rapidly increasing temperature of a fuel passage member, and also provide a fuel supply device which automatically controls the temperature of the fuel passage member below a specified temperature. CONSTITUTION:A coil bobbin 32 and a high frequency induction heating coil 33 wound around the coil bobbin 32 are provided on the periphery of a member 30 privided with a fuel passage 31, and PTC element which increases its resistance when a specified temperature is attained is serially connected to the high frequency heating coil. When high frequency current is run to the high frequency iduction heating coil 33, the fuel passage member 30 is heated in induction so as to increase its temperature in a short time, and when the fuel passage member 30 attains the specified temperature, the current running to the high frequency induction heating coil 33 is rogulated by the PTC element, then, heating of the fuel passage member 30 is suppressed, and the fuel passage member 30 is maintained at its specified temperature. |
