Abstract: The present invention relates to an electromagnetic shielding rack. More particularly, the present invention relates to an electromagnetic shielding rack which prevents the breakage and the malfunction of internal equipment due to an external electromagnetic wave when computation and communication equipment are installed in a computer room environment and prevents an electromagnetic wave generated in a shield rack from being leaked to the outside. For this, the present invention includes a shield rack which has a first door which is assembled with outer panels which form a receiving part inside - the outer panels are electrically connected to each other -, and allows one of the outer panels to be opened/closed, and a second door which allows at the other of the outer panels to be opened/closed, porous holes which penetrate at least one of the outer panels which form the shield rack, and a penetration wave guide which has a first penetration hole which penetrates at least one of the outer panels which forms the shield rack, and protrudes from the outer edge of the first penetration hole to the receiving part.
