Abstract

An ESD protection device includes a multilayer body including base material layers, a hollow portion inside the multilayer body, a ground electrode exposed at the hollow portion, first and second discharge electrodes exposed at the shared hollow portion and opposing the common ground electrode, and an auxiliary discharge electrode including conductive particles dispersed in the base material layer and extending along an inner surface of the hollow portion. At least the auxiliary discharge electrode in an adjacent region between the first discharge electrode and the second discharge electrode is divided into a portion on the first discharge electrode side and a portion on the second discharge electrode side by a non-formation section where the auxiliary discharge electrode is not provided in the hollow portion.
