Provided is a printed circuit board, including: a core substrate including an internal circuit pattern on an upper surface or a lower surface; electronic devices which are formed to pass through the core substrate; an external insulating layer which covers the internal circuit pattern and the electronic devices; and an external circuit pattern which is formed on an upper surface of the external insulating layer, wherein a lower surface of the electronic devices protrudes from the lower surface of the core substrate to a lower part. Accordingly, in the embedded printed circuit board in which the electronic devices are embedded, when the electronic devices are mounted, because the insulating layer is formed regardless of a thickness of the electronic devices, the printed circuit board having a desired thickness regardless of the thickness of the electronic devices can be formed.
