Abstract

A printed circuit board includes a core layer, a plurality of conductive pattern layers disposed on one side and the other side of the core layer, a plurality of insulating layers disposed on the one side and the other side of the core layer, and a plurality of via layers disposed on the one side and the other side of the core layer. The printed circuit board has a wiring region and a dummy region surrounding at least a portion outside of the wiring region on a plane. A metal ratio in the dummy region on one side and a metal ratio in the dummy region on the other side are different from each other.
