MANUFACTURING METHOD OF VARISTOR DEVICE AND VARISTOR DEVICE

摘要

To provide a varistor device that can be manufactured cost effectively.SOLUTION: A manufacturing method of a varistor device (100) includes a step of providing a substrate (1) including a ceramic material for a varistor device (100), a step of providing a base material for a base metal electrode region (2) on a substrate, a step of exposing the base material containing substrate (1) under a protective gas atmosphere under certain temperature conditions such that the base metal electrode region (2) is formed and firmly connected to the base material (1) of the varistor device (100).SELECTED DRAWING: Figure 1
