A method for preparing the sintered body of titanium boride being characterized in that 17-27 mol % of metallic titanium powder, 39-74 mol % of boron powder and 1-30 mol % of aluminium powder are wet combined in an anhydrous solvent and pressed at pressure of 500 kg/cm2 to obtain a desired molding. The molding is self burned by a discharge spark under an inert gas condition which is shut tight under a pressure of 1 atm and above to sinter a composite material with constituents of titanium boride 50-80%, boron nitride 10-40% and aluminium nitride 1-30%.
