Abstract
An ESD protection device has a structure that allows ESD characteristics to be easily adjusted and stabilized. The ESD protection device includes a ceramic multilayer substrate, at least a pair of discharge electrodes located in the ceramic multilayer substrate and facing each other with a space disposed therebetween, and external electrodes located on a surface of the ceramic multilayer substrate and connected to the discharge electrodes. The ESD protection device includes a supporting electrode disposed in a region that connects the pair of discharge electrodes. The supporting electrode is made of a conductive material coated with an inorganic material having no conductivity.
