熱抵抗体をメタライズすることは不可能であった。[Prior Art] Conventionally, resistor metallization methods for ceramic heaters include a method of wrapping a heating wire such as nichrome,
There have been methods such as co-firing a high-melting point metal such as tungsten, and forming a metal film using a thick film printing method. However, with either method, it has been impossible to metallize the heating resistor on the curved surface of the ceramic.

ルムである。[Means for Solving the Problems] The present invention involves creating a transfer film printed with a paste made of a mixture of metal powder and crystallized glass, transferring the transfer film onto a heat-resistant ceramic surface, and then heating the transfer film. This is a method of manufacturing a ceramic heater characterized by forming a heating resistor pattern by firing. A transfer film that can be suitably used in carrying out this method is a transfer film in which a paste consisting of a mixture of metal powder and crystallized glass is printed on a resin film, and the resin film is pasted on a water-absorbing mount. It's a film.

る。[0006] The steps after the paste printing step in the method of the present invention are similar to those used in general ceramic painting.
After kneading the binder, printing on the resin film and drying it, a backing paper is attached to create a transfer film.When used, the transfer paper is suspended in water, the film is lifted off the backing paper, and then peeled off. Apply water to printed matter. The type of ceramic is not limited, but alumina, silicon nitride, aluminum nitride, etc. are used. The ceramic surface to be metalized can be any curved surface, such as the outer or inner surface of a cylindrical shape such as a pipe or bottom-sealed tube, or the outer or inner surface of a dish, bowl, or pot shape. Of course, it can also be suitably used for flat parts and curved parts of flat plates.
