Abstract
Embodiments of the presently-disclosed subject matter include a first laminated structure in which at least one conductor layer and at least one resin insulating layer are alternately formed is formed on a supporting substrate, and a core substrate is formed so as to come into contact with the conductor layer which is the uppermost layer of the first laminated structure. Then, laser light is emitted to the core substrate to form a through hole and a metal layer is formed in the through hole. Then, a second laminated structure including at least one conductor layer and at least one resin insulating layer is formed on the core substrate. At that time, the thickness of the conductor layer which is the uppermost layer of the first laminated structure is greater than that of the other conductor layers.
