To provide a method for manufacturing a sensor element, by which stabilization of an electrode, which is performed prior to inspecting element characteristics, can be performed for a shorter time period and in a more reliable manner than in the conventional. A pre-treatment prior to inspection of electrical characteristics is performed on a sensor element for use in a gas sensor that measures a concentration of a predetermined gas component in a measurement gas. The sensor element includes: an oxygen-ion conductive solid electrolyte layer; a first electrode that is formed on a surface of the oxygen-ion conductive solid electrolyte layer; and a second electrode that is formed in a space provided inside the oxygen-ion conductive solid electrolyte layer, and that is configured to reduce said predetermined gas component. As the pre-treatment, by an external power source, a voltage is applied between the first electrode and the second electrode, to thereby decompose and remove a gas component attached to the second electrode. |
