Claim 14:
15. A printed circuit board comprising:
an insulating layer having first and second regions;
a connection pad of which at least a portion is embedded in one surface of the insulating layer in the first region, wherein a width of an exposed portion of the connection pad is substantially the same as a width of portions of the connection pad covered by the insulating layer;
a circuit pattern embedded in the one surface of the insulating layer in the second region; and
a surface treatment layer disposed on one surface of the connection pad,
wherein the insulating layer has a larger thickness in the second region than in the first region, and
wherein a roughness of an upper surface of the surface treatment layer is greater than a roughness of a side surface of the surface treatment layer.
