Abstract:
A method for manufacturing an O.sub.2 sensor element having a cup-shaped solid electrolyte member having an inside space with an opening, an outside electrode provided on an outside surface of the solid electrolyte member, and an inside electrode provided on an inside surface of the solid electrolyte member within the inside space, the method comprising steps of:preparing a nozzle having a paste discharge hole at a front end thereof, the paste discharge hole being for discharging conductive paste for forming the inside electrode;inserting the front end of the nozzle into the inside space of the solid electrolyte member;relatively rotating the paste discharge hole of the nozzle with respect to the solid electrolyte member along the inside surface of the solid electrolyte member while discharging the paste from the paste discharge hole onto the inside surface of the solid electrolyte member;removing the nozzle from the solid electrolyte member; andbaking the solid electrolyte member.
