Abstract: An electronic device and a shielding film are disclosed herein. The electronic device includes a printed circuit board and at least one electrical component mounted on the printed circuit board. The shielding film is disposed on at least a part of the printed circuit board to block electromagnetic waves generated by the printed circuit board and/or the electronic component. The shielding film includes a plurality of layers, and is attached to at least part of the printed circuit board and contacting an upper side surface of the electronic component, wherein at least part of the shielding film includes a nano-conductive fiber and is electrically connected with a ground part of the printed circuit board through the nano-conductive fiber.

Abstract: An electronic device including a shielding member for performing an electromagnetic interference (EMI) shielding function is provided. The electronic device includes a printed circuit board including a first area in which first electronic components having a first frequency as a driving frequency are mounted, and a second area in which second electronic components having a second frequency as a driving frequency are mounted, a shielding film disposed to cover the first area and the second area of the printed circuit board and attached to a first ground portion of the printed circuit board, and at least one conductive member formed to extend in a direction perpendicular to an extending direction of the printed circuit board. The at least one conductive member includes a first end that contacts the shielding film, and a second end that contacts a second ground portion of the printed circuit board, the second end being disposed between the first area and the second area of the printed circuit board.
