A metal base carbon fiber composite material which is produced by heating and pressing a metal and a carbon fiber, and has a structure wherein metal layers and metal layers containing a carbon fiber are laminated alternately; and a method for producing the above metal base carbon fiber composite material, which comprises a step of attaching carbon fibers onto a metal support in the form of a sheet or film to form a preform, a step of laminating a plurality of preforms to form a preform laminate, heating and pressuring the preform laminate under vacuum or in a non-oxidizing atmosphere to thereby integrate the preforms with one another. The above metal base carbon fiber composite material can be produced by the use of generally used non-expensive materials with the energy less than that used in the molten metal method, can have a wide range of dimension or shape (in particular, a large surface area), exhibits excellent thermal conductivity and also is lightweight.
