<p>PURPOSE:To ensure a resistance temperature coefficient by allowing a title composition to contain NiO, Cu, and specific glass. CONSTITUTION:A title composition contains 40-70 pts by weight NiO, 5-40 parts by weight Cu, and 5-50 pts by weight glass represented by a general formula a Li2O+bRO+cB2O3+(100-a-b-c) SiO2 (where R is at least one kind selected among Ng, Ca, Sr, and Ba, and a-c are molar %.) with a-c satisfying conditions: 0<=a<=20, 10<=b<55, and 0<=c<40. A resistor material containing said composition as paste is printed on an insulator ceramics green sheet and calcined in the non-oxidative atmosphere. Hereby, a thick resistor with a resistance temperature coefficient ranging within + or -300ppm/C can be manufactured.</p> |
