Patent ID: 7095310

Claim:
A non-linear resistor comprising 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, wherein an 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 a thickness of the side-surface high resistance layer+0.01 mm; the side-surface high resistance layer is formed of at least one element selected from substances containing, as a main substance, an inorganic polymer substance having electric insulating characteristics and heat resistance, an amorphous inorganic polymer substance, a glass compound, an amorphous inorganic substance, a crystalline inorganic substance, and an organic polymer compound, and the side-surface high resistance layer is adhered to the sintered body so as to have a shock adhesive strength of 40 mm or more, the shock adhesive strength being a height at which the side-surface high resistance layer is peeled off from the sintered body when the nonlinear resistor having the side-surface high resistance layer is tilted by an angle of 45 degrees to the horizontal surface and a ball of 100 g is dropped from the height to a corner portion of the nonlinear resistor to collide with the nonlinear resistor.
