Abstract
A functionally gradient material having desired characteristics without having any joining section is efficiently obtained by means of integration effected by a sintering treatment, the functionally gradient material comprising a metal part composition containing predetermined components based on a basic composition of tungsten and copper and a ceramic part composition containing predetermined components based on a basic composition of aluminum nitride and aluminum. Therefore, the metal and the ceramic are integrated into one unit without providing any joining section to give a high joining reliability and high thermal conductivity.
