ABSTRACT:
The present invention is an apparatus for filling a multi-powder including a powder box (10) including a plurality of powder chambers storing a plurality of powders whose constituent compositions differ in a divided manner, and a gas feed pipe (14) disposed on the bottom side of the powder chamber and having an introducing hole for introducing a gas, wherein it can fill a plurality of the powders into a cavity (24) at once through the bottom openings of the powder box by introducing a gas through the introducing hole to substantially equalize the respective flow resistances of a plurality of the powders. Thus, it is possible to fill the powders whose constituent compositions differ at once without disposing them in a mixed manner.
