PROBLEM TO BE SOLVED: To provide a method of manufacturing a laminated chip varistor capable of producing the laminated chip varistor having sufficient varistor characteristic even in the case of baking at a low temperature. SOLUTION: In the method of manufacturing the laminated chip varistor 1, mix powder obtained by mixing glass powder in the powder of a varistor material is used, so that a baking temperature in the case of baking is lowered. Moreover, in the manufacturing method, in a varistor element body obtained by baking a laminated body LS1, the quantity of Pr and Ag included in the grain boundary of grains containing ZnO as a main component is larger than the quantity of Pr and Ag included inside of the grains, high resistance in the grain boundary is obtained. Thus, the laminated chip varistor 1 having varistor characteristic sufficient for practical use is obtained even in the case of baking at a low temperature. COPYRIGHT: (C)2007,JPO&INPIT
