A heat sink has a base and multiple fins. The fins are attached to the base, and each fin has a radiating surface and a conducting surface. The conducting surface is formed on the radiating surface and has at least one side abutting the base. The base is attached to an integrated circuit to dissipate heat from the integrated circuit. Because at least one of the two sides of the conducting surfaces is in full contact with the base, more heat is conducted from the base to the fins. Therefore the heat sink can cool the integrated circuit effectively.
