摘要：A method of operation of a gas sensor includes applying a control voltage thatis repetitively set to on state and off state between the reference electrode and themeasurement-object gas side electrode to pump in oxygen to the periphery of thereference electrode; and detecting the specific gas concentration in the measurement-
object gas on the basis of a voltage between the reference electrode and the
measurement electrode during a second period, from among a first period that is startedupon setting of the control voltage to on state, during which a potential differencebetween the reference electrode and the measurement-object gas side electrode islarge, and the second period that is started upon setting of the control voltage to offstate after the potential difference falls from the first period.
