Abstract
A gas sensor includes a sensor element and a control unit for controlling the sensor element. The sensor element includes: an adjustment pump cell for adjusting an oxygen concentration in a measurement-object gas to a desired concentration; a current measurement pump cell for detecting a target gas to be measured in the measurement-object gas as a current value, the current measurement pump cell including: an inner measurement electrode and an outer measurement electrode; a reference electrode; and an electromotive force detection sensor cell for detecting an electromotive force value between the inner measurement electrode and the reference electrode. The control unit includes a switching unit for switching whether a current flows through the current measurement pump cell or not.
