Abstract
A voltage-nonlinear resistor elementincludes a voltage-nonlinear resistor (referred simply as 'resistor')and a pair of electrodesandbetween which the resistoris interposed. The resistorhas a multilayer structure including a first layercomposed primarily of zinc oxide, a second layercomposed primarily of zinc oxide, and a third layercomposed primarily of a metal oxide other than zinc oxide. The second layeris adjacent to the first layerand has a smaller thickness and a higher volume resistivity than the first layerThe third layeris adjacent to the second layer
