Abstract:
A thick-film resistor paste consisting of a mixture of a first glass powder, a second glass powder, a conductive material powder, and an organic vehicle, wherein a quantity of the first glass powder mixed is larger than a quantity of the second glass powder mixed, and the first glass powder has a thermal expansion coefficient larger and a glass transition point higher than the second glass powder, and wherein the first glass powder contains, in total, 95 percentage by weight or above of CaO of 20 to 26 percentage by weight, SiO.sub.2 of 37 to 59 percentage by weight, Al.sub.2 O.sub.3 of 5 to 13 percentage by weight and B.sub.2 O.sub.3 of 8 to 28 percentage by weight, and the second glass powder contains, in total, 85 percentage by weight or above of SiO.sub.2 of 53 to 72 percentage by weight, B.sub.2 O.sub.3 of 20 to 30 percentage by weight and Na.sub.2 O of 1 to 7 percentage by weight.
