Abstract

Provided are a thin electromagnetic shielding sheet and an electronic device having the same. The thin electromagnetic shielding sheet includes: a pressure-sensitive adhesive tape including a fiber-accumulating type substrate, formed by accumulation of a plurality of fibers and having a plurality of pores, and a metal coating layer on an outer circumferential surface of each of the plurality of fibers, and electrically conductive adhesive layers formed on both surfaces of the fiber-accumulating type substrate, and made of an electrically conductive adhesive material filled in the plurality of pores and electrically connected by an applied pressure; a metal layer which is adhered to the electrically conductive adhesive layer on one surface of the pressure-sensitive adhesive tape to shield electromagnetic waves; and an insulating layer formed on the metal layer.
