Abstract
A printed circuit board and an electronic product are disclosed. In accordance with an embodiment of the present invention, the printed circuit board includes a first board, which has an electronic component mounted thereon, and a second board, which is positioned on an upper side of the first board and covers at least a portion of an upper surface of the first board and in which an EBG structure is inserted into the second board such that a noise radiating upwards from the first board is shielded. Thus, the printed circuit board can readily absorb various frequencies, be easily applied without any antenna effect and be cost-effective in manufacturing.
