摘要： Provided is an ESD protection device having excellent discharge characteristics at a low applied voltage. An ESD protection device includes a first discharge electrode and a second discharge electrode that are disposed so as to face each other, a discharge auxiliary electrode formed so as to span between the first discharge electrode and the second discharge electrode, and an insulator base that holds the first discharge electrode, the second discharge electrode, and the discharge auxiliary electrode. The discharge auxiliary electrode includes a plurality of metal particles (22) containing a first metal as a main component. Fine irregularities are formed on the surfaces of the metal particles (22). More specifically, the metal particles (22) has a fractal dimension D of 1.03 or more. Since electric charges are concentrated on the fine irregularities, discharge can be generated in the discharge auxiliary electrode by applying a relatively low voltage.
