Abstract: A heat spreader includes a metal substrate and a plating layer covering a surface of the metal substrate. Multiple depressions and multiple projections are alternately arranged in the surface of the metal substrate covered by the plating layer.

Abstract: A heat transfer device includes a base material and a composite plating layer formed on the base material, wherein the composite plating layer includes metal and graphene particles dispersed in the metal.

Abstract: A radiation member includes a base material; and a composite plating layer, formed on the base material, that includes a metal layer and two or more kinds of carbon materials, having different diameters from each other, dispersed in the metal layer such that to be provided with a plurality of protruding portions, each of the protruding portions being composed by a part of each of the carbon materials that are protruded from a surface of the metal layer.

Abstract: In one embodiment, there is provided a composite plating liquid. The composite plating liquid includes: a plating metal salt; a sulfate of at least one element selected from alkali metals and alkaline earth metals; boric acid; a carbon nanotube; and a dispersant. Also, there is provided a plating method of plating a member using the composite plating liquid, and a composite plating film formed by the plating method.

Abstract: A heat radiating component includes a base including a first metal, a first plating layer formed on the base and including a second metal and carbon material structures dispersed in the second metal, and a second plating layer formed on the first plating layer. The first plating layer includes protruding parts that are parts of the carbon material structures protruding from a surface of the second metal. The second plating layer is formed on the first plating layer to cover surfaces of the protruding parts and the surface of the second metal without filling spaces between the protruding parts.

Abstract: In one embodiment, there is provided a heat radiating component. The heat radiating component includes: a base material made mainly of copper; an electroplated aluminum layer that covers at least a part of a surface of the base material; and an alumite layer formed on the electroplated aluminum layer and formed by anodic-oxidizing the electroplated aluminum layer.
