PROBLEM TO BE SOLVED: To provide a varistor which realizes not only low varistor voltage and low electrostatic capacity but low dielectric loss, and is excellent in ESD suppression effect and resistance thereto and suitable as ESD measures for various electronic devices.SOLUTION: A voltage nonlinear resistor composition contains ZnO as a chief constituent and is represented by the general formula (1-x)ZnO+xSr(MnCo)O, where x, y and a represent a molar ratio and are in range represented by 0.0005≤x≤0.10, 0≤y<0.20 and -0.1≤a≤0.2. This composition realizes not only low varistor voltage and low electrostatic capacity but low dielectric loss, and also realizes excellent ESD suppression effect and resistance thereto. |
