Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a circuit structure comprising lamination and a plurality of internal flat surfaces of high wiring-density. SOLUTION: A method of manufacturing a circuit structure comprises a step, where an organic substrate 12 comprising a circuit 14 over it is provided, a step for coating a dielectric film 30 on the organic substrate 12, a step for forming a micro via in the dielectric film 30, a step for sputtering a metal seed layer 20 on the dielectric film 30 and in the micro via, a step for placing a metal layer 22 on the metal seed layer 20, and a step for forming a circuit pattern over it.
