ABSTRACT:
An air/fuel ratio (A/F) sensor for detecting the A/F over a wide range covering a lean region and a rich region which are partitioned by the stoichiometric A/F comprises a solid electrolyte made of an oxygen ion conductive metal oxide, first and second electrodes sandwiching the solid electrolyte and being operable by a predetermined voltage applied thereacross to ionize oxygen near the solid electrolyte and diffuse oxygen ions into the solid electrolyte, and a gas diffusion layer in the form of a porous sintered layer covering the second electrode and made of electrically insulative metal oxide fine particles having a mean particulate size of 1 .mu.m or less so that oxygen or molecules of other gas components in the exhaust gas can move through pores of the gas diffusion layer.
