Beschreibung
Zusammenfassung:	An aluminum-copper clad member includes an aluminum-base member, a copper-base member and an insertion member made of pure aluminum or JIS A1xxx series aluminum alloy. The aluminum-base member and the copper-base member are clad via the insertion member. A heat sink includes a heat radiation portion made of aluminum-base material and provided with a plurality of tongue-like fins formed by skiving a surface layer of one side of the heat radiation portion and a thermal diffusion portion made of copper-base material and joined to the other side of the heat radiation portion via an insertion member made of pure aluminum or JIS A1xxx series aluminum alloy.
