Claim:
1. A printed circuit board comprising: a core substrate having a cavity; a first internal circuit pattern on an upper surface of the core substrate; a second internal circuit pattern on a lower surface of the core substrate; an electronic device which is mounted in the cavity to pass through the core substrate; an upper insulating layer configured to cover the first internal circuit pattern and the electronic device at an upper part of the core substrate; a lower insulating layer configured to cover the second internal circuit pattern and the electronic device at a lower part of the core substrate; and an external circuit pattern formed on a surface of the upper insulating layer and a surface of the lower insulating layer, wherein a lower surface of the upper insulating layer is in direct contact with an upper surface of the core substrate, wherein an upper surface of the lower insulating layer is in direct contact with an lower surface of the core substrate, wherein an upper surface of a terminal of the electronic device is positioned at a higher level than an upper surface of the first internal circuit pattern, and positioned at a lower level than an upper surface of the upper insulating layer, and wherein a lower surface of the terminal of the electronic device is positioned at a lower level than a lower surface of the second internal circuit pattern, and positioned at a higher level than a lower surface of the lower insulating layer.
