PROBLEM TO BE SOLVED: To provide a particle aggregate production method capable of obtaining particle agglomerate low in particle agglomerate content as compared with a conventional method. SOLUTION: The particle aggregate production method comprises the steps of preparing particle aggregate containing particles separated and independent from one another and particle flocculate, and sucking the particle aggregate into suction holes of a suction die by using the suction die having a plurality of the suction holes with the aperture diameter slightly wider than the particle diameter of the particles and the depth slightly deeper than the particle diameter of the particles. While suction is continued, an adhesive material is brought into contact with the surface of the suction die to remove the excess matter adhering to the die surface. The suction is stopped, and the particles sucked in the suction holes are separated from the suction die. COPYRIGHT: (C)2009,JPO&INPIT
