摘要

A combustible gas concentration measuring apparatus 70 includes a motor electromotive force detecting portion 75 configured to acquire information about an electromotive force of a mixed potential cell 55 while a detecting electrode 51 is exposed to a target gas, an oxygen concentration detecting portion 76, which is the one The control section 72 derives the concentration of a combustible gas pin to the target gas from the detected information about the electromotive force EMK, the detected information about the oxygen concentration p, and the relationship represented by the formula (1), from:
