PROBLEM TO BE SOLVED: To provide a granulation method for providing a desired granular material by precisely determining the granulation finishing even in the case of alteration of the load weight of a powder granule to a granulator at the time when granulation of the powder granule with which the granulator is loaded is carried out by stirring. SOLUTION: Correlation of a load weight of a powder granule to a granulator and the resistance value corresponding to the stirring resistance of the powder granule in the granulator with one of the aiming granule diameter, the aiming bulk density, and the aiming production yield of a granulated material is previously computed. The resistance value is computed from the previously computed correlation of one of the aiming granule diameter, the aiming bulk density, and the aiming production yield with the measured load weight. Granulation is finished at the time when the measured resistance value reaches the computed resistance value.
