A shielding structure for suppressing electromagnetic interference in a printed circuit board has at least a pad. A chip is disposed on the printed circuit board and a heat sink is disposed on the chip. The shielding structure includes a main body and a sidewall. In this case, the main body has a contacting portion and an opening. The contacting portion is in contact with the heat sink and one part of the heat sink protrudes from the main body via the opening. The sidewall is encircled around the main body. The sidewall is connected to the main body, has a connecting portion electrically connected to the pad. The main body, the sidewall, and the printed circuit board form a containing space, and the chip is disposed in the containing space.
