PROBLEM TO BE SOLVED: To provide a gas concentration measuring apparatus, capable of preventing zero-point variations in the presence of a gas to be detected and the sensitivity of a detection element from changing, even if the ambient temperature changes, and capable of also detecting gases different from the gas to be detected, and which has high detection accuracy to gas components of low concentrations of approximately 500 ppm or lower, and to provide a program and a method. SOLUTION: The gas concentration measuring apparatus measures the concentration of the gas to be detected, on the basis of the changes in a resistance value of the detection element 2a in the absence of the gas to be detected and in the presence of the gas to be detected. The gas concentration measuring apparatus 1 is provided with an element resistance setting means 3 that makes the detection element 2a and a compensation element 2b have resistance values, corresponding to a predetermined element temperature at any atmospheric temperature, in the absence of the gas to be detected.
