Abstract: An A/F sensor element includes a substrate made of an insulating ceramic having a bottomed cylindrical shape, an electrolyte part made of a solid electrolyte, and a pair of electrode portions. The electrolyte part is embedded in at least a portion of the side wall of the substrate. The A/F sensor element is used by inserting a rod-like heater in the substrate having the bottomed cylindrical shape. The substrate is formed of the insulating ceramic at a contact position to the heater within the substrate. In a manufacturing of the substrate, a molded body having a space for a forming position of the electrolyte part is formed by using substrate-forming clay, and then the molded body is molded by filling electrolyte-forming clay into the space.

Abstract: A gas sensor element includes a basal body, at least one solid electrolyte portion and a pair of electrodes. The basal body has a bottomed tubular shape and is made of an electrically insulative ceramic material. The basal body has a side wall and a bottom wall. The at least one solid electrolyte portion is formed in the bottom wall or the side wall of the basal body. The pair of electrodes are opposed to each other with the at least one solid electrolyte portion interposed therebetween. The difference in surface level between the basal body and the at least one solid electrolyte portion at a boundary therebetween is less than or equal to 30 μm.

Abstract: A gas sensor element includes an insulating ceramic base, a solid electrolyte body, and a heating element. The solid electrolyte body is disposed in an opening of the insulating ceramic base and has a measuring electrode affixed to one of major surfaces thereof and a reference electrode affixed to the other major surface. The measuring electrode is exposed to gas to be measured. The reference electrode is exposed to a reference gas. The heating element works to activate the solid electrolyte body and is mounted on one of opposed surfaces of the insulating ceramic base on the same side as the major surface of the solid electrolyte body on which the reference electrode is disposed. Specifically, the insulating ceramic base is located between the solid electrolyte body and the heating element, thereby ensuring a desired degree of electric insulation between the heating element and the reference electrode.
