[Summary] [Problems] To provide extremely-spherical-three-dimensional-shaped particles of crystalline mannitol containing large hollows and gaps inside. [Solution] Spherical particles of crystalline mannitol made by spray drying, extremely spherical (having an aspect ratio of 1.0 to 1.2), high oil absorption rates according to test method A, wherein powder has a mean particle diameter of 15 to 165 μm, a loose bulk density of 0.35 to 0.60 and an angle of repose of 30 to 50 degrees, and has a hardness of 7 to 20 kgf, when directly compressed.
