Claims

[Scope of Claim for Utility Model Registration] (1) In a heat sink for an electric element in which a fin mounting plate is provided upright on a metal substrate on which a heat generating component is mounted, and a plurality of fins are provided on the fin mounting plate, A bulge is formed along the longitudinal direction of the fin, and each of the plurality of fins is provided with a notch hole that approximately matches the cross-sectional outer circumferential shape of the fin mounting plate, and a joining piece is provided protruding from the edge of the notch hole. A heatsink for an electric element, which is formed by fitting fins on the outer periphery of a fin mounting plate and attaching them at appropriate intervals. (2) The heat radiator for an electric device as set forth in claim (1) of the utility model registration claim, characterized in that the bulging portion of the fin mounting plate is hollow and the diameter of the bulging portion is enlarged.
