ABSTRACT:
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.
