摘 要：
PROBLEM TO BE SOLVED: To provide a gas sensor with improvement in the measurement accuracy
realized.;SOLUTION: This gas sensor for specifying a concentration of a predetermined gas component in a measurement gas, on the basis of a current flowing in an oxygen ion conductive solid electrolyte by the
decomposition of the predetermined gas component, includes an internal space to which the measurement gas is introduced from an external space; a reference gas space to which a reference gas is introduced; a pumping cell provided, capable of pumping out oxygen in the internal space, by applying a
predetermined voltage between a first electrode formed on the surface of the internal space and a second electrode formed on a space different from the internal space; and a measuring cell
provided, capable of measuring a current flowing between a measuring electrode and a reference electrode, by applying a
