PROBLEM TO BE SOLVED: To provide a coated granule containing a bioactive component having an excellent performance.SOLUTION: The coated granule is obtained by providing a coated layer on the surface of a granular substance containing a bioactive component. The coated layer is constituted of a resin-coated layer containing a thermosetting resin or a thermoplastic resin, and a protection layer containing 12-hydroxystearic acid on the outside of the resin-coated layer. A coated granule with an alkyl sulfate on the surface has an excellent performance.
