  • Patent number: 10241074
    Abstract: Provided is a gas sensor having excellent detection sensitivity and responsiveness. In a sensor element, 3.5?D2/D1?6 is satisfied, where D1 is a value of a diffusion resistance of a measurement gas via a main gas distribution part extending from an outside edge position of a first gas inlet to the second internal space, and D2 is a value of a diffusion resistance of a measurement gas flowing via a second gas inlet that causes the outside and the second internal space to communicate with each other. The concentration of a predetermined gas component contained in the measurement gas through the second gas inlet is determined on the basis of a potential difference between the sensing electrode and a reference electrode, while pumping oxygen in or out for the measurement gas via the main gas distribution part such that the oxygen concentration of the second internal space is maintained at 1 vol % or more.
