ABSTRACT:
Several heater patterns are printed on a ceramic green sheet for substrates, and the ceramic green sheet is laminated with a ceramic green sheet for cover plates, thereby forming a lamination body. Then, the lamination body is cut so that it is divided into several intermediate bodies, each of which holds a corresponding one of the heater patterns therein and has a side surface on which a terminal portion of the heater pattern is exposed. Then, the intermediate body is baked. As a result, a ceramic heater composed of a heater substrate holding the heater pattern and a cover plate disposed on the heater substrate to cover the heater pattern can be provided without any micro-cracks therein.
