Abstract
The invention provides a method for manufacturing an oxygen sensor that is excellent in responsiveness and can be preferably used for diagnosis of catalyst deterioration. An oxygen sensorequipped with an oxygen sensor elementcomprising a solid electrolyteand Pt coatings, as a pair of electrodes, on both surfaces of the solid electrolyteis manufactured. The method comprises at least steps of: providing a Pt coatingon at least one of the solid electrolytesurfaces exposed to the gas to be tested so as to form closed poresinside the Pt coating; and heating either the Pt coatingorexposed to gas to be tested in a gas atmosphere with higher oxygen concentration than that of the atmospheric gas.
