    摘要: An ESD protection device includes opposed electrodes in a ceramic base material and a discharge auxiliary electrode in contact with each of the opposed electrodes which is arranged so as to provide a bridge from the opposed electrode on one side to the opposed electrode on the other side, the discharge auxiliary electrode includes metallic particles, semiconductor particles, and a vitreous material, and bonding is provided through the vitreous material between the metallic particles, between the semiconductor particles, and between the metallic particles and the semiconductor particles. The metallic particles have an average particle diameter X of about 1.0 μm or more, and the relationship between the thickness Y of the discharge auxiliary electrode and the average particle diameter X of the metallic particles satisfies about 0.5≦Y/X≦ about 3.
