摘要： A gas sensor is provided with a multilayer body of solid electrolyte layers, a measurement electrode, a reference electrode, a reference gas introduction layer, a detection unit and a heater. The reference electrode and the measurement electrode are formed directly on the same first solid electrolyte layer. Thus, heat from the heater is transferred from a third substrate layer to the first solid electrolyte layer, and also to the reference electrode and the measurement electrode through the same first solid electrolyte layer. The reference electrode is covered with a reference gas introduction layer, formed of a porous body. The transference of heat from the heater to the reference electrode through the reference gas introduction layer is smaller than the transference of heat from the heater to the reference electrode through the first solid electrolyte layer on which the reference electrode is formed directly.

摘要： A NOx sensor 100 includes a sensor device 110 and a heater 70 capable of heating the sensor device 110. The sensor device 110 includes an inner pump electrode 22 and an outer pump electrode 23 disposed respectively on the inner side and the outer side of a solid electrolyte layer 6. The sensor device 110 detects the concentration of NOx by introducing a gas to be measured into a first inner vacancy 20, pumping out oxygen in the gas to be measured from the inner pump electrode 22 to the outer pump electrode 23, introducing the gas to be measured, from which the oxygen has been pumped out, into a second inner vacancy 40, reducing the NOx in the gas to be measured, to thereby generate oxygen, and detecting the generated oxygen. A characteristic stabilizing layer 24 covers the outer pump electrode 23 and is made of a porous body with a thickness of 10 to 200 μm and a thickness variation of 20% or less.

摘要： A gas sensor includes an internal space, diffusion control part, pumping cell, and measuring cell. The diffusion control part communicates with the internal space and has a slit-like shape with a smaller thickness than that of the internal space. The pumping cell pumps out oxygen from the internal space when voltage is applied between a first electrode formed on a surface of the internal space and a second electrode formed outside the internal space. The measuring cell measures a current flowing between a third and fourth electrodes when a voltage is applied between the third and fourth electrodes. The third electrode is formed in the diffusion control part, and can reduce an oxide gas component in a predetermined gas component to which a predetermined diffusion resistance has been applied by the diffusion control part. The fourth electrode is formed in a part different from the diffusion control part.
