A heat sink is provided to increase the maintenance of the heat sink and the convenience of storage by constructing various types of heat sinks by combining more than one heat discharging plates formed in a predetermined standard. A heat sink(10) includes at least one heat discharging plate(100,200,300), a connection unit(20), and a fixing rib(30). The heat sink discharges heat generated at a circuit device fixed on a PCB(Printed Circuit Board). The heat discharging plates are formed in a predetermined standard. The connection unit is formed on a specific position of each heat discharging plate. The fixing rib is formed together with the heat discharging plates. The fixing rib fixes the heat discharging plates on the PCB.
