A fuel evaporator comprises a ring-shaped heater element made of PTC ceramic, a pipe made of heat conductive metal and disposed within an air-fuel passage of an internal combustion engine therealong and a pair of terminal members for supplying power to the heater element. The heater element is disposed closely in contact with the outer periphery of the upper end of the pipe. One end of each of the pair of terminal members is closely in contact with each of the upper and under surfaces of the heater element. The fuel evaporator further comprises a plate-shaped compact made of electricity insulating rubber or synthetic resin and formed around the upper end of the pipe. Within the compact, the heater element, the upper end of the pipe and the terminal members are embedded.
