Abstract
An ESD protection device includes a ceramic base material, a pair of opposed electrodes provided on a surface of or in the ceramic base material, and a discharge auxiliary electrode film arranged to connect the pair of opposed electrodes, wherein the discharge auxiliary electrode film is composed of a material containing, as its main constituents, metallic particles and glass covering the metallic particles. The discharge auxiliary electrode film is formed by providing an electrode paste containing glass-coated metallic particles that have an approximately 15% rate of increase in weight at about 400° C. for about 2 hours in air, a resin binder, and a solvent so as to connect the pair of opposed electrodes to each other, and then firing at a temperature of about 600° C. or more, higher than a softening point of glass of the glass-coated metallic particles, and not +200° C. higher than the softening point.
