Abstract
A heat sink can include a fin using graphite, and a base with a high heat dissipation film formed on its surface to be provided with a high heat dissipation performance. The heat sink can include a base made of metal and a fin fixed to the base. The fin can include a graphite sheet. The base has a surface coated with a film having a higher heat dissipation property than that of the metal constituting the base. The film of the base is removed from at least the region where the fin is fixed, so that the fin is fixed to the metal constituting the base.
