PURPOSE:To obtain the titled composition having small variability of resistance value and thermistor constant and small change of resistance value with time, by adding Bi as a secondary component to a main component consisting of Mn, Ni, Cu, Co and Zr. CONSTITUTION:A main component consisting of oxide solid solutions of Mn, Ni, Cu, Co and Zr is blended with 0.1-10mol% Bi element as a secondary component and, if necessary, 0.1-10atom.% one or more elements selected from Li, B, Mg, Al, Si, Ti, V, Cr and Zn. |
