Abstract
A voltage nonlinear resistor ceramic comprises: a Zn oxide; a Co oxide; an R (specific rare earth) oxide; a Cr oxide; an M1 (Ca, Sr) oxide; an M2 (Al, Ga, In) oxide; and strontium titanate. When content of the Zn oxide is assumed to be 100 mole portion in terms of Zn, content of the Co oxide is 0.30 to 10 mole portion in terms of Co, content of the R oxide is 0.10 to 10 mole portion in terms of R, content of the Cr oxide is 0.01 to 2 mole portion in terms of Cr, content of the M1 oxide is 0.10 to 5 mole portion in terms of M1, content of the M2 oxide is 0.0005 to 5 mole portion in terms of M2, and content of the strontium titanate is 0.10 to 5 mole portion in terms of SrTiO.
