PROBLEM TO BE SOLVED: To provide a voltage nonlinearity resistor composition that develops excellent voltage nonlinearity even when an unbaked varistor material and a less noble electrode having low resistance are burned integrally with each other, and enables dense sintering.SOLUTION: A voltage nonlinearity resistor composition contains Zn element, Co element, Ta element and first Sr element, and at least one kind of element or element group selected from the group consisting of second Sr element, Ca element and Ba element. The first Sr element is coupled to the Co element. When the element or element group selected from the group consisting of the second Sr element, the Ca element and the Ba element is represented by A, and with respect to the mole ratios of the Zn element, the Co element, the first Sr element, the Ta element and A, the mole ratio of the Zn element is represented by (1-x), the mole ratios of the Co element and the first Sr element are represented by x, the mole ratio of the element of A is represented by y and the mole ratio of Ta is represented by Z, x, y and z are in a range satisfying 0.0025≤x≤0.05, 0.002≤y≤0.05 and 0≤z≤0.003.SELECTED DRAWING: Figure 1 |
