An object of the present invention is to provide an ESD protection device and the like which offer a reduced discharge starting voltage and improved durability against repeated use. The present invention provides an ESD protection device including a base 2 having an insulating surface 2a, electrodes 3a and 3b disposed on the insulating surface 2a and facing but spaced apart from each other, and a functional layer 4 disposed on at least between the electrodes 3a and 3b, wherein the gap distance &Dgr;G between the electrodes 3a and 3b ranges from 0.5 μm to 10 μm, and the thickness &Dgr;T of each of the electrodes 3a and 3b meets a relationship of &Dgr;G/&Dgr;T=1 to 30. |
