Abstract

An electro-static discharge (ESD) protection structure includes a first insulation layer (having a first surface, a second surface opposite to the first surface, and a through hole), a patterned conductive layer (located on the first surface), an electro-static releasing layer (located on the second surface), and a solder mask layer. At least one portion of the patterned conductive layer surrounds the through hole. The electro-static releasing layer is electrically insulated from the patterned conductive layer. At least one portion of the electro-static releasing layer is around the through hole. The solder mask layer covers the first insulation layer and a portion of the patterned conductive layer and exposes a portion of the patterned conductive layer surrounding the through hole. A multi-layered circuit board including a second insulation layer, a power supply layer, a third insulation layer and the ESD protection structure is also provided.
