Abstract
A gas sensor element includes a cup-shaped solid electrolyte body having closed and open ends, a reference electrode provided on an inner surface of the solid electrolyte body, and a measurement electrode provided on an outer surface of the solid electrolyte body. The reference electrode has a detection portion located closer to the closed end than to the open end of the solid electrolyte body, a terminal portion located closer to the open end than to the closed end of the solid electrode body, and a lead portion connecting the detection and terminal portions. Moreover, the reference electrode has a first thickness in a large-thickness region and a second thickness smaller than the first thickness in a small-thickness region. The large-thickness region includes at least part of the detection portion of the reference electrode, and the small-thickness region includes at least the lead and terminal portions of the reference electrode.
