ESD PROTECTION DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

An ESD protection device having high insulation reliability and excellent discharge characteristics is provided. In an ESD protection device including a first and a second discharge electrode disposed to face each other, a discharge auxiliary electrode (18) formed so as to bridge the first and second discharge electrodes, and an insulating substrate holding the first and second discharge electrodes and the discharge auxiliary electrode (18), the discharge auxiliary electrode (18) is formed of an aggregate of metal grains (24) each having a core-shell structure comprising a core portion (22) primarily formed of a first metal and a shell portion (23) primarily formed of a metal oxide containing a second metal, and the aggregate of metal grains (24) further includes an insulating resin (27) which bonds the metal grains (24) to each other.
