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 a portion exposed in the cavity, the exposed portions being arranged to face each other, and external electrodes provided on a surface of the insulating substrate and connected to the at least one pair of discharge electrodes. A particulate supporting electrode material having conductivity is dispersed between the exposed portions of the at least one pair of discharge electrodes in the cavity.
