Abstract
A gas sensor includes a sensor element including an adjustment pump cell and a measurement pump cell, and a control unit including a pump control part. The pump control part performs a startup pump control at a startup of the sensor element, and a steady driving pump control at a steady drive after the startup. In the startup pump control, the pump control part applies, between an inner pump electrode and an outer pump electrode of the adjustment pump cell, a startup voltage of the adjustment pump cell that is higher than a voltage applied in the steady driving pump control; and applies, between an inner measurement electrode and an outer measurement electrode of the measurement pump cell, a startup voltage of the measurement pump cell that is higher than a voltage applied in the steady driving pump control and lower than the startup voltage of the adjustment pump cell.
