METHOD FOR MANUFACTURING MULTILAYER VARISTOR AND MULTILAYER VARISTOR

A method for manufacturing a multilayer varistor includes: a first step including providing a multilayer stack in which a plurality of green sheet layers, each containing a Zn oxide powder as a main component and a Pr oxide powder as a sub-component, and a plurality of internal electrode paste layers, each containing a Pd powder, are alternately stacked; and a second step including forming a sintered compact, including an internal electrode inside, by baking the multilayer stack. The second step includes: a first sub-step including baking the multilayer stack by setting an oxygen concentration in an atmosphere at 1000 ppm by volume or less while increasing a temperature from 500° C. to 800° C.; and a second sub-step including baking, after the first sub-step, the multilayer stack by setting the oxygen concentration in the atmosphere at 1000 ppm by volume or more while increasing the temperature to a maximum allowable temperature.
