Abstract
A gas sensor includes a solid electrolyte substrate that has oxygen-ion conductivity, and a counter plate, made of ceramic, that is arranged so as to face a first surface of the solid electrolyte substrate. The gas sensor further includes a first spacer, made of ceramic, that is held between the counter plate and the solid electrolyte substrate, a heater substrate, made of ceramic, that is arranged so as to face a second surface of the solid electrolyte substrate, and a second spacer, made of ceramic, that is held between the heater substrate and the solid electrolyte substrate. Of the counter plate, the sintered density of an inside portion that comes in contact with a measurement-gas chamber is 0.8 to 5.0% lower than the sintered density of an outside portion that comes in contact with the first spacer.
