Abstract: There is provided an ESD protection device capable of lowering a discharge starting voltage. An ESD protection device 1 includes a ceramic multilayer substrate 2, a first discharge electrode 4 and a second discharge electrode 5 arranged at a height position of the ceramic multilayer substrate, an end 4a of the first discharge electrode 4 and an end 5a of the second discharge electrode 5 facing each other, in which each of the first discharge electrode 4 and the second discharge electrode 5 contains a metal and a shrinkage suppression material having a lower rate of shrinkage than that of the metal at a temperature at which firing for the production of the ceramic multilayer substrate 2 is performed.
