Abstract
In a sensor element, oxygen contained in a gas to be measured introduced into a first internal spacethrough a first diffusion control partis pumped out by applying voltage between an inner pump electrodeand an outer pump electrode. After the oxygen is pumped out, NOx in the gas to be measured generates oxygen by being reduced by a measurement electrode. This oxygen is pumped by applying voltage between the measurement electrodeand the outer pump electrode. On the basis of current generated according to the amount of oxygen thus pumped, the NOx gas concentration is calculated. A slit width of the first diffusion control parton an entrance side is larger than a slit width on an exit side.
