<p>PURPOSE:To obtain a thick film resistor composite, wherein a ceramic substrate for low temperature firing and a resistor are able to be simultaneously fired so as to reduce the number of firing, being able to incorporate a resistor and to widen a mounting area and having an excellent high voltage characteristic by adding a specific amount of an Ni compound to RuO2 powder and to glass powder of a borosilicate alminocalcium system or the like. CONSTITUTION:0.5-7.0wt.% of an Ni compound as Ni is added to a total wt.% of RuO2 powder and glass powder of 10-55wt.% of MO (provided M is Ca or Mg), 45-70wt.% of SiO2, 0-30wt.% of Al2O3 and 0-30wt.% of B2O3. As said Ni compound, various kinds of Ni chloride, for instance, of Ni NiO or an organic Ni compound can be used. For instance, the Ni compound as Ni is mixed with a total 100wt.% of 15-25wt.% of RuO2 powder and the rest of borosilicate glass (32wt.% of CaO, 4wt.% of Al2O3, 42wt.% of SiO2 and 22wt.% of B2O3) powder at a blending rate of 0.5-7.0wt.% and a terpineol solution containing ethyl cellulose as an organic vehicle is added so as to obtain a thick film resistor composite.</p> |
