Abstract

An NOx sensor for an exhaust gas is made from .beta.-Nb.sub.2 O.sub.5 as a primary component and TiO.sub.2 as a subsidiary component. The TiO.sub.2 content is in a range of 0.1% by weight .ltoreq.TiO.sub.2 .ltoreq. 20% by weight. In place of TiO.sub.2, Ru may be used in the NOx sensor. The Ru content is in a range of 0.1% by weight .ltoreq.Ru.ltoreq. 10% by weight. Thus, the NOx sensor has an excellent NOx adsorbing ability and is higher in sensitivity to NOx in an exhaust gas.
