Abstract
Solid cellulose particles contain cellulose as a main component. The cellulose particles have a volume average particle diameter D of from 1 μm to 30 μm inclusive and a circularity of 0.86 or more. A value A represented by the following formula (1) is less than 0.15: (wherein, in formula (1), D is the volume average particle diameter (μm) of the cellulose particles, and S is a BET specific surface area (m2/g) of the cellulose particles). A = 1 / ( D × S ) formula ( 1 )
