temperature variation of capacitance variation in characteristics of the city provides a small voltage non- linear resistor element. Voltage non-linear resistor element layer (2 ) include a sintered body having ZnO as a main component ( ceramics ) is used. The sintered body has Pr, Co, Ca, and Na are , respectively , Pr is 0.05 to 5.0 atom %, Co is 0.1 to 20 atomic %, Ca 0.01 to 5.0 atom %, Na is added in the range of 0.0001 to 0.0008 at% the . In this range , the temperature change rate of capacitance in a 25 85 relative to the case of a can to be not more than 10%.
