ABSTRACT:
A gas sensor for measuring a quantity of specific component in a measuring gas includes a main pump means which has an electrochemical pump cell. The electrochemical pump cell includes a solid electrolyte partition exposed to external space, an inner pump electrode and an outer pump electrode formed on the inner surface and outer surface of the solid electrolyte partition, respectively. The main pump means treats oxygen contained in the measuring gas introduced from the outer space by pumping processing on the basis of a control voltage applied between the inner pump electrode and the outer pump electrode. An RLC element which has a specific electric characteristic value corresponding to a characteristic value of the electrochemical pump cell is connected in parallel with the electrochemical pump cell.
