Abstract:
To solve a problem of a conventional heat sink that if force is applied to a fin plate, a heat radiation fin is fallen over causing difficulty to assemble the heat sink.SOLUTION: A heat sink according to the present invention includes first leg parts provided at one surface side of surfaces included in a fin plate; and a second leg part provided at the other surface side facing the one surface. In the heat sink according to the present invention, the leg parts are provided on both surfaces of the fin plate.
