PROBLEM TO BE SOLVED: To provide a composite material having excellent thermal conductivity and being free from peeling between a carbon material, such as carbon nanotube and vapor grown carbon fiber, and a matrix metal and also to provide a manufacturing method therefor. SOLUTION: An aluminum sheet 11 and a carbon/metal compound material 12 in which the surface of the VGCF 12a as the carbon material is coated with a coating metal 12b composed of Cu or Ni are alternately laminated to form a laminate 13, then rolling is applied to the laminate 13 while heating the laminate 13 in a vacuum atmosphere, and thus the high thermal conductivity composite material 10 in which the VGCF 12a is uniformly dispersed in metal Al constituting the aluminum sheet 11 and the carbon material and the metal Al as the matrix metal are firmly bonded, can be manufactured.
