Abstract:
A voltage non-linear resistor ceramic composition has ZnO as a main component and is represented by the general formula (1−x)ZnO+x[Sr1−yMy]1−a[Co1−zAz]1+aO3. Here, M is at least one of Ca and Ba, and A is Mn or Cr. x, y, z and a indicate molar ratios, and 0.0005≦x≦0.10, 0≦y≦0.8, 0≦z≦0.8, and −0.1≦a≦0.2 are satisfied.
