Abstract:
On a cross sectional surface X 1  of a pump electrode  3  in a gas sensor element forming a gas sensor, a noble metal area  31  having Pt—Au aggregations, a solid electrolyte area  32  having solid electrolyte aggregations, a mixture area in which Pt—Au alloy and solid electrolyte are distributed, and pores  34 . The mixture area  33  is formed within a range of 30 to 90% in an overall area of the cross sectional surface X 1 , excepting the pores  34 . The pores are formed adjacent to the mixture area  33.

Claim (Index 1):
A pump electrode for a gas sensor, formed on a target gas-side surface of a solid electrolyte body having ion conductivity, the target gas-side surface being exposed to a target gas to be measured, the pump electrode decomposing oxygen contained in the target gas into oxide ions by an electric power supplied to the pump electrode, the oxide ions passing through the solid electrolyte body and being discharged to a reference gas-side surface of the solid electrolyte body which is arranged in opposite in position to the target gas-side surface, wherein\n the pump electrode is made of Pt\u2014Au alloy and a solid electrolyte made of ceramic material which is the same type of ceramic material forming the solid electrolyte body, a first noble metal area, a first solid electrolyte area, a first mixture area and first pores are formed in the pump electrode, and a cross section of the pump electrode is cut along a thickness direction of the pump electrode, wherein Pt\u2014Au alloy aggregations are formed in the first noble metal area, solid electrolyte aggregations are formed in the first solid electrolyte area, and a mixture of Pt\u2014Au alloy and the solid electrolyte is formed in the first mixture area, and the first mixture area has an area within a range of 30 to 90% in an overall area of the cross section, excepting an area of the first pores, on the cross section of the pump electrode, and the first pores are formed adjacent to the first mixture area.
