Polysaccharide fine particles that can be prepared under mild conditions that do not affect the survival of cultured cells, have a wide range of applications, and are excellent in biocompatibility, and a method for producing the same I will provide a. SOLUTION: Polysaccharide fine particles obtained by crosslinking a polysaccharide polymer compound via a phenolic hydroxyl group and having an average particle diameter of 0.01 to 5,000 μm are obtained. For its preparation, an aqueous solution in which a phenolic hydroxyl group-containing polysaccharide polymer compound having a phenolic hydroxyl group as a functional group is dissolved and / or dispersed, an enzyme capable of oxidizing the phenolic hydroxyl group, liquid paraffin, To form an emulsion. An aqueous solution in which an amino group-containing polysaccharide polymer compound having an amino group as a functional group is dissolved and / or dispersed; a polyphenol compound; and an enzyme capable of oxidizing a phenolic hydroxyl group of the polyphenol compound; Mix with liquid paraffin to form an emulsion.
