Abstract
Cellulose particles include mother particles, containing cellulose as a principal component; and a coating layer that coats the mother particles, in which the average circularity of the cellulose particles is 0.97 or more, and the relation between carbon atom amount Cs and oxygen atom amount Os in the cellulose particles measured by X-ray photoelectron spectroscopy satisfies the formula A1: Cs/Os≥2.0.
