Abstract
An ESD protection device includes an insulating ceramic body including a cavity, first and second discharge electrodes disposed so as to partially face each other with the cavity interposed therebetween, and a supporting electrode disposed so as to be at least partially exposed to the cavity and to be electrically connected to the first and second discharge electrodes. A void isolated from the cavity is provided in at least a portion of a boundary region between at least one of the first and second discharge electrodes, the supporting electrode, and the insulating ceramic body.
