<p>A method of manufacturing a heat sink material, comprising the steps of putting graphite in a case (70) and storing the case in a furnace (Step S301), baking the inside of the furnace (60) so as to manufacture a porous sintered body (12) with graphite (Step S302), taking out the porous sintered body (12) as contained in the case (70) from the furnace (60), and storing the porous sintered body (12) as contained in the case (70) in a recessed part of a press (62) (Step S303), pouring a molten metal (86) of a metal (14) in the case (70) (Step S304), and inserting a punch (84) into the recessed part so as to press down the molten metal (86) in the case (70) for press-fitting (Step S305), whereby the molten metal (86) of the metal (14) is soaked in open porous parts of the porous sintered body (12) by the pressing of the punch (84).</p> |
