Abstract:
A voltage nonlinear resistor ceramic composition comprises zinc oxide, with respect to 100 mol of said zinc oxide, 0.30 to 10 mol of Co oxide in terms of Co, 0.10 to 10 mol of R oxide (note that R is at least one selected from a group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) in terms of R, 0.10 to 5 mol of Cr oxide in terms of Cr, 0.10 to 5 mol of oxide of at least one selected from Ca and Sr respectively in terms of Ca or Sr, 0.0005 to 5 mol of oxide of at least one selected from Al, Ga and In respectively in terms of Al, Ga or In, and 0.10 to 5 mol of barium titanate in terms of BaTiO3.
