<p>An object of the present invention is to provide an ESD protection device which is excellent in discharge capacity, at the same time, causes fewer short circuit defects, requires no special step for manufacture, and is excellent in productivity, and a method for manufacturing the ESD protection device. In an ESD protection device including: a ceramic base material 1 including a glass component; opposed electrodes 2 including an opposed electrode 2a on one side and an opposed electrode 2b on the other side, which are formed so as to have their ends opposed to each other at a predetermined distance in the ceramic base material; and a discharge auxiliary electrode 3 between the opposed electrodes, which is connected to each of the opposed electrode on one side and the opposed electrode on the other side, and placed so as to provide a bridge from the opposed electrode on one side to the opposed electrode on the other side, a sealing layer 11 for preventing the ingress of the glass component from the ceramic base material into the discharge auxiliary electrode is provided between the discharge auxiliary electrode and the ceramic base material.</p> |
