The present invention provides resin beads that can provide various types of products, such as a cosmetic having excellent tactile impression, spreadability on the skin, and transparency, that can be substituted for resin particles composed of a synthetic material derived from petroleum, and that have favorable biodegradability, and the present invention also provides various types of products, such as a cosmetic using the resin beads. The resin beads are formed with a resin containing cellulose as a main component. The resin beads have a cumulative 50% particle size on a volume basis of 50 μm or smaller, a degree of sphericity of 0.7 to 1.0, a degree of surface smoothness of 70 to 100%, a degree of solidity of 50 to 100%, and a biodegradation rate for 5 days, as measured in accordance with JIS K6950:2000 (ISO 14851:1999), of 20% or more, and the content of the cellulose in the resin is 90 to 100% by mass. In addition, the present invention provides a product of any one of a cosmetic, a dermatological preparation, a paint, a shaped article, a film, a coating agent, and a resin composition which contain the resin beads.
