PROBLEM TO BE SOLVED: To easily work a compacting die with a complicated shape, to superiorly maintain current efficiency and to improve the density of a green compact or a sintered compacted article such as a sintered compact. SOLUTION: A compacting die 75, which is used to obtain a green compact or a sintered compact by mixing powder materials in a prescribed ratio, feeding the mixed powder materials into a die and carrying out electrification while applying pressure, has the following characteristics: the compacting die 75 is constituted of upper and lower punches 33 and 31 and a die 76; and, with respect to the die 76, an outer member 78 is attached to an inner member 77 via an insulation layer 79 and the inner member 77 and the outer member 78 are composed of cemented carbide or die steel.
