摘要： A ceramic heater which can be produced easily, induces no increase of production cost and can restrict the resistance change of a heating body due to migration. According to the present invention, a gap is formed between a ceramic sintered body and a heating body. Thus, migration in which cations are seized within the gap is caused so as to impede the cations from entering into the heating body. This makes it difficult for the cations to migrate and the volume in which the heating body is expanded is secured by the gap 13.

摘要： In a method for forming an inside electrode within a cup-type electrolyte member of an O.sub.2 sensor element, firstly, a nozzle having a paste discharge hole is prepared. The nozzle is inserted into an inside space of the electrolyte member. Then, the paste discharge hole of the nozzle is relatively rotated with respect to the electrolyte member along an inside surface of the electrolyte member while discharging paste therefrom onto the inside surface. Accordingly, the inside electrode formation portion is formed. After forming the inside electrode formation portion, the electrolyte member is baked. As a result, the inside electrode can be disposed on a required portion of the electrolyte member with a uniform thickness.
