Abstract: A printed circuit board (PCB) is provided as follows. A first connection pad and a second connection pad are disposed on a first surface and a second surface of the base substrate layer, respectively. The first connection pad and the second connection pad each includes a first metal. A first pad cover layer covers a top surface of the first connection pad and includes an insulating metal oxide having a second metal different from the first metal.
