Abstract
A method of producing a thin film heating element is provided which can be used in manufacturing a transparent thin film heating element of desired shape with an increased heat emission property and an excellent durability. Also provided is a heating device of the type incorporating the thin film heating element produced by this method. The inventive method comprises the steps of, applying heat- and oil-resistant ink on a predetermined surface area of a base element, allowing the ink to run dry, spraying conductive chemical composition on the base element to form a conductive thin heater film, removing the ink out of the base element, printing a thin film electrode leading to the thin heater film, and baking the base element into a thin film heating element.
Claims11
A method of producing a thin film heating element, comprising the steps of:
- masking a surface of a material except a heat generating portion with heat- and oil-resistant ink and allowing the ink to run dry;
- preheating the material and spraying a conductive composition for the thin film heating element on a surface of the preheated material using clean air as a carrier to form a conductive thin film for the thin film heating element;
- removing the ink from the material by water cleaning;
- printing the conductive thin film for the thin film heating element with a conductive thin film for an electrode and then drying the conductive thin film for the electrode;
- and
- baking the material.
