PURPOSE: A fuel heating device of a fuel filter is provided to prevent inrush current from passing through a contact point of a temperature switch when the contact point is restricted. CONSTITUTION: A fuel heating device of a fuel filter comprises a fuel heater(1) and a temperature switch(5). The fuel heater is installed in the fuel filter. The temperature switch is installed at the head(3) of the fuel filter and controls the electric current supplied to the fuel heater based on the measured temperature. According to the heat-sensitive switch is the temperature of the head metalized surface of the fuel filter, it is installed so that the electrical contact of the inside is regulated. The temperature switch is installed to restrict an electric contact point inside according to the temperature of air around the head of the fuel filter. The temperature switch is in parallel with the fuel heater, and the electric currents passing through the fuel heater and temperature switch are independently formed. A relay is formed between the temperature switch and the fuel heater. [Reference numerals] (AA) B-B cross section
