Abstract
A resistor is provided which comprises an insulation substrate, a resistive layer prepared from inorganic materials and printed on the insulation substrate, and an insulation layer prepared from borosilicate lead glass and overcoated on the resistive layer. The insulation layer contains an oxide of at least one transition metal selected from the group consisting of iron, nickel, chromium, cobalt, zinc, copper, zirconium, and cadmium. In the course of operation, the resistor of the present invention exhibits no changes in its resistance, irrespective of the length of time it may be operated.
