Abstract
A film heating element includes a substrate, an electrothermal film layer coated on a surface of the substrate and made of a material having a PTC effect, and two electrodes mounted on two opposite sides of the electrothermal film layer and each electrically connected to the electrothermal film layer. Thus, the film heating element has a simplified construction and does not need a temperature control.
