Abstract:
The present invention provides an ESD protection device and the like having improved durability against repeated use. An ESD protection device includes a base having an insulating surface, electrodes disposed on the insulating surface and facing but spaced apart from each other, and a functional layer disposed on at least between the electrodes. The electrodes have a multistage structure in which a gap between the electrodes is narrower toward the base.
