Abstract
A circuit board includes a substrate, a first dielectric layer, an adhesive layer, a second dielectric layer, and a conductive line. The first dielectric layer is disposed on the substrate. The adhesive layer is bonded to the first dielectric layer and has at least one through hole. The through hole has an inner wall. The second dielectric layer is disposed on the adhesive layer and has a second through hole communicated with the first through hole. The conductive line is located in the second through hole of the second dielectric layer and is in contact with the inner wall of the adhesive layer.
