<；P>；PROBLEM TO BE SOLVED: To provide a coated granular material which is prevented from floating on a water surface in the application, does not adversely affect the elution rate of biological active substance after long storage and produces small amount of dust in the operation. <；P>；SOLUTION: The coated granular material is a biological active substance granular material which has a coating layer comprising a resin composition. The coated granular material is formed by holding metallic salt of fatty acid or a metallic salt of the fatty acid and inorganic power on the surface of the coating layer. The metallic salt of the fatty acid is a 8-22C metallic salt of the fatty acid having &ge；100°；C melting point or the mixture thereof and the ratio of the metallic salt of the fatty acid or the mixture thereof to the whole coated granular material is preferably 0.01-0.2 wt.%. The ratio of the inorganic powder to the whole coated granular material is preferably 0.01-0.3 wt.%. <；P>；COPYRIGHT: (C)2010,JPO&INPIT
