A nonlinear resistor ceramic composition has a major component containing zinc oxide, a first minor component containing an oxide of a rare-earth metal, a second minor component containing an oxide of Ca, and a third minor component containing an oxide of Si. A percentage of the second minor component to 100 moles of the major component is in the range of 2 atomic %≦̸the second minor component<80 atomic % in terms of Ca. A percentage of the third minor component to 100 moles of the major component is in the range of 1 atomic %≦̸the third minor component<40 atomic % in terms of Si. An atomic ratio of Ca to Si (Ca/Si) is not less than 1.
