Abstract:
1. A circuit board comprising: a first electronic component having a first external surface and a second external surface opposite to each other, the first electronic component having a first conductor disposed on said second external surface, the first electronic component having a first hole extending therethrough from the first external surface to the second external surface, and the first electronic component having a second conductor disposed in the first hole; a substrate having a third surface on which the second external surface of the first electronic component is mounted and a fourth surface opposite the third surface, the substrate having a second hole extending therethrough from the third surface to the fourth surface; a first insulation layer laminated on the third surface of the substrate, the first insulation layer having a fifth surface facing the substrate and a sixth surface opposite the fifth surface, the first insulation layer having an opening extending therethrough from the fifth surface to the sixth surface, the first electronic component provided in the opening; a second insulation layer laminated on the first insulation layer; a third conductor disposed in the second hole; and a wiring pattern provided on the fourth surface and electrically coupled to the first electronic component through the second conductor and the third conductor, wherein the first external surface of the first electronic component is a planar surface, and the first external surface is coplanar with said sixth surface of said first insulating layer.
