A film resistor heater comprising a sprayed film resistor comprisng NiCr particles uniformly dispersed and partly contacted with each other in an insulating ceramic matrix. The film resistor heater may further comprise a bonding layer, an insulating layer and a protective layer. The film resistor heater is prepared by spraying, particularly plasma spraying. It may be used advantageously for home electric appliances such as hot plates, rice cookers and vacuum kettles, heat rolls for electrostatic copiers, etc. |
