Abstract:
A gas sensor S which detects a concentration of a specific gas contained in a gas to be measured is provided with a gas sensor element. The gas sensor element has an ion conductive solid electrolyte body, a measuring gas electrode which is mounted on a surface of the solid electrolyte body, a reference gas electrode mounted on a surface of the solid electrolyte body, and a catalyst layer mounted on an outer-side relative to the measuring gas electrode-side. The catalyst layer contains a metal catalyst loaded onto a carrier. The metal catalyst is a Pt single substance, and has a specific surface area defined by the equation below of equal to or more than 0.01 to equal to or less than 23. Specific surface are=total surface area of metal catalyst which exists on an electrode unit surface area/actual surface area of electrode per electrode unit surface area.  Equation 1:

Claim (Index 1):
A gas sensor comprising;\n a gas sensor element detecting a concentration of a specific gas contained in a measuring gas; the gas sensor element provided with\n a solid electrolyte body having oxide ion conductivity, the solid electrolyte body having a first surface and a second surface; \n a measuring gas electrode disposed on the first surface the measuring gas electrode being exposed to the measuring gas; \n a reference gas electrode disposed on the second surface of the solid electrolyte body, the reference gas electrode being exposed to reference gas; and \n a catalyst layer which contains a metal catalyst loaded onto a carrier; the catalyst layer having gas permeability and being mounted on an outer-side position relative to the reference gas electrode, wherein \n the metal catalyst is a single substance and a specific surface area of the metal catalyst is 0.01 or more and 23 or less, and the specific surface area is expressed in an equation 1 below.\n Specific surface area=total surface area of the metal catalyst which exists on top of an electrode unit surface area/an actual electrode surface area per electrode surface area.\u2003\u2003Equation 1:
