    摘要： An oxygen sensor element includes a solid electrolyte having cavities on a surface thereof and an electrode formed on the surface of the solid electrolyte. In a method of producing the oxygen sensor element, a solution containing a noble metal compound for nucleus formation is first applied to an electrode forming portion of the solid electrolyte to form a coating film. Then, the coating film is heat-treated to form a nucleus forming portion where noble metal nuclei are deposited. Subsequently, metal plating is applied to the nucleus forming portion to form a plating film deeply entering the cavities. Thereafter, the plating film is burned to form the electrode deeply entering the cavities.

    摘要： A measuring electrode and a reference plate are formed on the front and rear surfaces, respectively, of the electrolytic plate. The vent plate is provided with a vent channel. The heater base comprises a heating element. The electrolytic plate is made of a green sheet of zirconium oxide consisting of 5 to 7 molar % Y.sub.2 O.sub.3 and 0 to 5 parts by weight of aluminum oxide. The average particle diameter of the zirconium oxide powder is less than 2.0 .mu.m. The green sheet of zirconium oxide has a thickness of 50 to 300 .mu.m. The heater base is made of a green sheet of aluminum oxide consisting of aluminum oxide powder having an average particle diameter of less than 1.0 .mu.m and 0 to 10 parts by weight of zirconium oxide or yttria-stabilized zirconium oxide. The green sheet of aluminum oxide is at least 4 times the thickness of the green sheet of zirconium oxide. To complete the oxygen sensor, these four components are sintered together at 1300.degree. to 1600.degree. C. to be integrated.

    摘要： An air-fuel ratio sensing element comprises a pump cell having at least one pair of pump electrodes thereon, a sensor cell having at least one pair of sensor electrodes thereon, and a gas chamber having two surfaces defined by the pump cell and the sensor cell. Two to five gas holes, each having approximately the same diameter and communicating with the gas chamber, are provided for introducing sensed gas into the gas chamber. The gas holes form their projection images on the surface of the sensor cell which has a sensor electrode thereon and faces the gas chamber. The sensor electrode is shaped such that it is dividable into a plurality of similar subsections defined by virtual lines connecting the geometric centroid of the sensor electrode and the center of the projection image of each gas hole.
