Abstract
According to the present invention, there is provided a carbon-based metal composite material comprising a carbonaceous matrix and a metal component dispersed in said carbonaceous matrix, wherein at least 90 volume percent of the pores of the carbonaceous matrix is substituted with said metal component, and the content of said metal component is 35% or less based on the total volume of said carbon-based metal composite material; a method of producing a carbon-based metal composite material wherein impregnation of the carbon formed body with molten metal under pressure is carried out by pre-heating said carbon formed body and then impregnating the open pores of the carbon formed body with molten metal under a pressure of at least 200 kg/cm of the cross-sectional area of the plunger; and a substrate-shaped formed body for an electronic component comprising a carbon-based metal composite material.
