A formed body prepared by compacting tungsten powders is embedded in a powder mixture capable of performing combustion synthesis, a part of the powder mixture is powerfully heated to ignite the part and perform combustion synthesis, by the heat of formation released, a temperature of a formed body is instantaneously elevated to induce a sintering reaction, and a high temperature state is retained to convert a whole of the formed body into sintered tungsten.
