Abstract
A gas sensor control apparatus including a gas sensor element, a heater for heating the gas sensor element, and heater energization control means for feedback controlling the supply of electric current to the heater such that the internal resistance of the gas sensor element coincides with a target resistance. The gas sensor element has a solid electrolyte member and an electrode portion including an outside electrode and an inside electrode. At least a portion of the electrode portion is formed of an electrically conductive oxide whose main component is (i) a first perovskite phase which is represented by a composition formula of LaCoNiO(0.300≤x≤0.600, 0≤d≤0.4) and has a perovskite-type crystal structure, or (ii) a second perovskite phase which is represented by a composition formula of LaFeNiO(0.450≤y≤0.700, 0≤d≤0.4) and has a perovskite-type crystal structure.
