Abstract

A printed circuit board includes a first insulating layer; a first wiring layer having at least a portion buried in one surface side of the first insulating layer and having at least a portion of one surface exposed from the one surface of the first insulating layer; a metal post disposed on the exposed one surface of at least the portion of the first wiring layer; and a second wiring layer disposed on the other surface of the first insulating layer. A width of a first surface, connected to the exposed one surface of at least a portion of the first wiring layer, of the metal post, is greater than a width of a second surface of the metal post opposing the first surface.
