A heat sink (100) includes a plurality of metal fins (10) interlocked with each other by interlocking units (11) formed between them. The interlocking units each include a protruding finger (122), a hole (114) and a controlling member (116, 117). The protruding finger, the hole and the controlling member are aligned with each other. The protruding finger includes a connecting tab (112a) which extends from a flange (14) of the metal fin and a locking tab (112b) which is curved inwardly from the connecting tab towards a main plate (12) of the metal fin. The locking tab of a rear metal fin extends into the hole of a front metal fin and fittingly abuts with the controlling member of the front metal fin so as to firmly interlock the rear and front metal fins together.
