Abstract
An electromagnetic interference shielding device includes a printed circuit board, a metal member and an elastic member. The elastic member includes a first resisting portion which contacts the printed circuit board and a second resisting portion which contacts the metal member, and the second resisting portion is saw-toothed, and is capable of piercing an oxidized layer of the metal member. Thus, the elastic member keeps contacting the metal member maximally no matter the metal member is oxidized or not, and reduces the electromagnetic interference effectively.
