An ESD protection device having high insulation reliability and good discharge properties is provided. In producing an ESD protection device that includes a first discharge electrode and a second discharge electrode arranged to oppose each other, a discharge supporting electrode formed so as to span between the first and second discharge electrodes, and an insulator substrate that retains the first and second discharge electrodes and the discharge supporting electrode, a paste for forming a discharge supporting electrode is used and this paste contains, in addition to a powder of an alkali metal compound and/or an alkaline earth metal compound, a metal powder with a network-forming oxide adhered to particle surfaces, a metal powder and a semiconductor powder with a network-forming oxide adhered to particle surfaces, or a metal powder with a network-forming oxide adhered to particle surfaces and a semiconductor powder with a network-forming oxide adhered to particle surfaces. |
