摘要： A non-linear resistor comprises a sintered body having zinc oxide as a main component, a side-surface high resistance layer arranged at a side-surface of the sintered body, and an electrode arranged at upper and lower surfaces of the sintered body. The side-surface high resistance layer is formed of a specifically selected material. The end-to-end distance between an end portion of the electrode and a nonlinear resistor end portion including the side-surface high resistance layer falls within a range of 0 mm to the thickness of the side-surface high resistance layer+0.01 mm.
