Abstract
An ESD protection device is manufactured such that its ESD characteristics are easily adjusted and stabilized. The ESD protection device includes an insulating substrate, a cavity provided in the insulating substrate, at least one pair of discharge electrodes each including an exposed portion that is exposed in the cavity, and external electrodes provided on a surface of the insulating substrate and connected to the discharge electrodes. Supporting electrodes obtained by dispersing conductive powder in an insulating material defining the insulating substrate are provided along a bottom surface and a top surface that define the cavity between the exposed portions of the at least one pair of discharge electrodes.
