According to an embodiment of the present invention, a printed circuit board comprises: a multilayered circuit substrate on which at least one base substrate is sequentially stacked; an extension unit formed by extending each one side of the at least one base substrate provided to an upper portion of the multi-layered circuit substrate, in one direction; a connection terminal; and a penetration via, wherein the extension unit is mutually attached by prepreg. The purpose of the present invention is to prevent the extension unit from being torn, when components are mounted on the printed circuit board. |
