Abstract: A manufacturing method of the circuit board includes the following steps. A metal layer, a first substrate, a second substrate, and a third substrate are laminated. Multiple blind holes and a through hole are formed. A conductive material layer is formed, which covers the metal layer, the conductive layer of the third substrate, and an inner wall of the through hole, and fills the blind holes to define multiple conductive holes. The conductive material layer, the metal layer, and the conductive layer are patterned to form a first external circuit layer located on the first substrate and electrically connected to the conductive pillars, and a second external circuit layer located on the insulating layer and electrically connected to the conductive holes, and define a conductive through hole structure connecting the first external circuit layer and the second external circuit layer and located in the through hole.

Abstract: An interlayer connective structure is suitable for being formed in a wiring board, in which the wiring board includes two traces and an insulation part between the traces. The insulation part has a through hole. The interlayer connective structure located in the through hole is connected to the traces. The interlayer connective structure includes a column and a pair of protuberant parts. The protuberant parts are located at two ends of the through hole respectively and connected to the column and the traces. The protuberant parts stick out from the outer surfaces of the traces respectively. Each of the protuberant parts has a convex curved surface, in which the distance between the convex curved surface and the axis of the through hole is less than the radius of the through hole.
