Abstract
An ESD protection deviceincludes a ceramic insulating material, first and second discharge electrodesand, and a discharge auxiliary section. The discharge auxiliary sectionis an electrode configured to reduce a discharge starting voltage between the first discharge electrodeand the second discharge electrode. The discharge auxiliary sectioncomprises a sintered body including conductive particles and at least one of semiconductor particles and insulating particles. At least the discharge auxiliary sectioncomprises at least one of an alkaline metal component and a boron component. The content of at least one of the alkaline metal component and the boron component in the discharge auxiliary sectionis larger than the content of at least one of the alkaline metal component and the boron component in the ceramic insulating material
