A heat radiating fin includes a flat body, two flange portions formed at two opposite edges of the flat body, and two inward bent locking ends formed at two lateral ends of each of the flange portions to space from the flat body by a distance. When two or more of the heat radiating fins are stacked to form a thermal module, the locking ends of a second heat radiating fin extend beyond the first heat radiating fin via the spaces between the locking ends and the flat body of the first heat radiating fin to upward abut against the flat body of the first heat radiating fin, so that the first heat radiating fin is firmly held to the second heat radiating fin.
