PROBLEM TO BE SOLVED: To provide an electric heating type pressurize-sintering device allowing a heating body to generate sufficient Joule heat, in the case of enlarging the diameter of the heating body corresponding to the large sintered body. SOLUTION: The electric heating type pressurize-sintering device is provided with a mold 3 having a molding space 2 for pressure-molding powder 1 in the inner part, an upper side heating body 9 and a lower side heating body 10 fitted to the molding space 2 in the mold 3 from the upper and the lower parts, a supporting means 7 for supporting the mold 3 and the lower side heating body 10, a pressurizing means 6 for giving the upper side heating body 9 the pressure force and an electric source 8 which is connected to the pressurizing means 6 and the supporting means 7. In such a case, the upper side heating body 9 and the lower side heating body 10 are constituted of electric conductive body parts 9a, 10a having required electric resistance and insulating body parts 9b, 10b. |
