Abstract
A spherical particle of the present invention contains a sugar alcohol and a crystalline cellulose and/or powdered cellulose, wherein the mass ratio between the sugar alcohol and the crystalline cellulose and/or powdered cellulose is within a range from 50:50 to 90:10, the particle size is within a range from 75 to 250 μm, the sphericity is not less than 0.8, and the bulk density is not less than 0.6 g/ml. Further, a method for producing the spherical particle of the present invention includes a granulation step of rolling a sugar alcohol having an average particle size of not more than 40 μm and a crystalline cellulose and/or powdered cellulose having an average particle size of not more than 50 μm while spraying a liquid thereon.
