ESD PROTECTION DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

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.
