Heat sink with heat dissipating fins and method of manufacturing heat sink

A heat sink comprising:

• a plurality of plate-like metal fins comprising a heat receiving portion and a heat dissipating elastic portion, said fins being linear or bent along a specific configuration;
• a fin fixing member to transfix said plurality of metal fins;
• a metal shield plate having a plurality of slits including linear and/or curved portions into which said respective fins are inserted along said slits, and press-connected to said fins by forming a first concave portion on a top side of said metal shield plate, a second concave portion on a bottom side of said metal shield plate, and an enlarged portion at the edge of said metal shield plate, wherein said first concave portion is aligned with said second concave portion at a given position on the metal shield plate;
• and
• a deformed portion of said metal shield plate being fixed with said heat dissipating portions which are inserted into said respective slits and fixed thereto;
• wherein each of said slits has a substantially same width corresponding to a thickness of said fins such that said slits are substantially filled by said fins.
