PROBLEM TO BE SOLVED : To provide granules having excellent fluidity, and capable of attaining the improvement in the dimensional precision of a compact and the improvement of productivity, or the like.
SOLUTION : The granules are obtained by binding a plurality of grains with an organic liquid. The granules are suitably used for powder metallurgy, particularly for producing a rare earth sintered magnet. In the granules, the organic liquid is interposed at least in the contact parts of the plurality of grains.
