Disclosed herein is a method of manufacturing a film heater. The film heater is used for domestic or industrial purposes. The method includes a first step of forming a heat-resistant crystallized glass under a heating element to stably absorb and dissipate heat generated by the heating element; a second step of forming a wiring part on the heat-resistant crystallized glass to supply power to the heating element; a third step of forming the heating element in a specific pattern to generate heat when electric power is applied thereto; and a fourth step of forming a ceramic protective layer in an uppermost part of the film heater to protect and insulate patterns of the heating element and the wiring part.
