摘要：
A sensing electrode for sensing a predetermined gas component of a measurement gas, which is provided in a mixed-potential gas sensor that measures the concentration of the predetermined gas component, is formed of a cermet containing a noble metal and an oxygen-ion conductive solid electrolyte. The noble metal comprises Pt and Au. An Au abundance ratio, which is an area ratio of a portion covered with Au to a portion at which Pt is exposed in a surface of noble metal particles forming the sensing electrode, is 0.3 or more.
