摘要：A sensor includes a pump cell and a reference cell generating voltage Vs orcurrent. The pump cell includes a pump cell first electrode and a pump cell secondelectrode. The surface of the pump cell first electrode includes a noble metal region

formed of a noble metal, a ceramic region, and a coexistence region in which the noblemetal and the ceramic material coexist. The width of the coexistence region in an A regionof the surface of the pump cell first electrode is greater than the width of thecoexistence region in a B region of the surface. The A region is a region close to thereference cell first electrode, and the B region is a region located further away from thereference cell first electrode as compared with the A region.
