Abstract
A composite material being excellent in heat conductivity is provided. In order to realize this, a fibrous carbon material made of fine tube form structures constituted with single-layer or multiple-layer graphene is present to form a plurality of layers within a substrate made from a spark plasma sintered body of a metal powder, a mixed powder of a metal and ceramics, or a ceramic powder. The fibrous carbon material constituting each layer is made of a mixture obtained by mixing a small amount of a small diameter fiberhaving an average diameter of 100 nm or less with a large diameter fiberhaving an average diameter of 500 nm to 100 μm.
