Abstract
Abstract A resistive paste consists essentially of a solid component dispersed in an organic vehicle, the solid component consisting essentially of 5 to 70 parts by weight of a resistor material, and 30 to 95 parts by weight of nonreducing vitreous material. The resistor material has a composition expressed by the general formula: Nb.sub.x La.sub.1-x B.sub.6-4x wherein x is a mol fraction of Nb and takes a value within the following range: 0.1≦x≦0.9.
