Abstract
A heat-dissipating fin of a large area is made of a metallic sheet and has a fin body. An outer edge of one side of the fin body extends to form a sheet-like expanding portion. The expanding portion is bent and overlapped on the fin body to obtain the heat-dissipating fin. A heat sink includes a plurality of heat-dissipating fins and a heat-conducting element, which is formed by means of penetrating the respective heat-dissipating fins with a condensing section of the heat-conducting element.
