    • PROBLEM TO BE SOLVED: To detect SOx contained in an exhaust gas.SOLUTION: An exhaust-component gas detector comprises an oxygen pump cell and a sensor cell. The oxygen pump cell has a first solid electrolyte forming a part of an exterior wall of a space into which an exhaust gas is introduced and a pair of electrodes that hold the first solid electrolyte therebetween and are disposed in such a manner that one of the electrodes contacts the space. The sensor cell has a second solid electrolyte forming a part of an exterior wall of the space, a pair of electrodes that hold the second solid electrolyte therebetween and are disposed in such a manner that one of the electrodes contacts the space, and a SOx absorbing and storing section provided on the electrode contacting the space. A voltage to regulate the concentration of oxygen in the space is applied to the oxygen pump cell. A voltage to decompose SOx is applied to the sensor cell. When current is applied to the sensor cell after a predetermined period of time when application of current is stopped, the amount of SOx or the concentration of SOx is estimated depending on an output from the sensor cell.
