Abstract: A coreless substrate having a plurality of function pads, etched from a metal sheet and having a protruded shape; an insulating layer, the insulating layer being formed on one side of the function pads, a circuit corresponding to a pattern being formed on the insulating layer, a via hole being formed on the insulating layer to electrically connect the function pads and the circuit; and a solder resist, being formed on the insulating layer to protect the surface of the insulating layer. The coreless substrate has a signal delivery characteristic that is improved by eliminating the inner via hole.
