The present invention relates to a gas sensor, and a method for measuring the concentrations of a plurality of target components in a gas to be measured. The gas sensor is provided with: an oxygen concentration control means (100) for controlling the oxygen concentration in an oxygen concentration adjustment chamber (18); a temperature control means (102) for controlling the temperature of a sensor element (12); a condition setting means (104) which sets the oxygen concentration of the oxygen concentration adjustment chamber (18) and/or the temperature of the sensor element (12) to conditionscorresponding to the types of target components in the introduced gas to be measured; and a concentration calculation means (106) which calculates the concentrations of the different target componentson the basis of the respective sensor outputs obtained under the plurality of conditions corresponding to the types of target components. 本发明涉及气体传感器以及被测定气体中的多个目标成分的浓度测定方法。气体传感器具有：氧浓度控制机构(100)，其对氧浓度调节室(18)内的氧浓度进行控制；温度控制机构(102)
