Abstract
A gas sensor element includes a solid electrolyte body having oxygen ion conductivity, a measurement electrode provided on one surface of the solid electrolyte body and exposed to a measurement gas, and a reference electrode provided on the other surface of the solid electrolyte body and exposed to a reference gas. Both the measurement electrode and the reference electrode include noble metal particles, solid electrolyte particles having oxygen ion conductivity, and pores. The measurement electrode comprises a surface measurement electrode layer comprising a surface serving as a contact surface with the measurement gas and an intermediate measurement electrode layer disposed in contact with a surface at solid electrolyte body side of the surface measurement electrode layer. The surface measurement electrode layer has a higher porosity than the intermediate measurement electrode layer has. The gas sensor comprises the gas sensor element.
