Abstract
A printed circuit board includes a first insulating layer, a first conductor-pattern layer disposed on one surface of the first insulating layer, a first recess formed in the other surface of the first insulating layer opposing one surface of the first insulating layer, a second conductor-pattern layer disposed in the first recess, and a first metal post penetrating the first insulating layer, connecting the first and second conductor-pattern layers to each other, and having one end exposed to a bottom surface of the first recess, wherein the second conductor-pattern layer includes a seed layer disposed on at least a portion of each of a surface of one end of the first metal post exposed to the bottom surface of the first recess and an internal surface of the first recess including the bottom surface of the first recess, and a plating layer disposed on the seed layer to fill at least a portion of the first recess.
