PTC HEATING DEVICE ABSTRACT OF THE DISCLOSURE A PTC heating device adapted to be used as a heat source for an electric vaporizer which is adapted to heat liquid medicine, e.g., liquid insecticide, aromatic liquid, or the like, to vaporize it. The PTC heating device comprises a casing in which an electrode structure including at least one PTC thermistor having electrodes arranged on both surfaces thereof and two electrode members interposing the PTC thermistor therebetween is received. The PTC heating device further includes a heat-radiating member mounted through a heat-conducting member with respect to the casing and for heating an absorber having sucked up liquid medicine from a reservoir having the liquid medicine contained therein to vaporize the liquid medicine. One of the electrodes of the PTC thermistor is in close contact with an flat surface of the heat-conducting member through one of two electrode member, so that heat generated at the PTC thermistor is efficiently transmitted to the heat-radiating member through the heat-conducting member.
