Abstract

The present invention relates to not only further increasing the adhesion between an oxygen ion conducting solid electrolyte and an oxide electrode, but to also improving the sensitivity of a sensor. The present invention relates to a method for manufacturing a NOx gas sensor, and to a NOx gas sensor manufactured using same, wherein the method comprises the steps of: preparing an oxygen ion conductive green sheet; preparing a paste which consists of a solvent, first powders made of metal oxide, second powders made of polymer, and a binder; coating the green sheet with the paste; sintering the green sheet to allow the green sheet to form an oxygen ion conducting solid electrolyte; and sintering the paste to allow the paste to form a metal oxide electrode which contacts the solid electrolyte.
