Abstract
The invention relates to glaze resistors which are used for electronic parts of hybrid integrated circuit devices, chip resistors, resistor network, etc. The glaze resistor comprises 4.0 to 70.0 wt % of a conductive component composed of a metal silicide and a metal boride and 30.0 to 96.0 wt % of glass in which a rate of said metal boride is 1.0 to 68.0 wt %. Thus, the glaze resistor can be formed by sintering in a non-oxidizing atmosphere and can provide a circuit, together with conductor pattern of base metals such as Cu.
