摘要： Provided herein is a cellulose nanofiber that can be easily combined with a compound having a reactive double-bond group and that can provide a molded article which contains only a small amount of an uncured material that acts as a plasticizer in a molded product, using a simple producing method that does not require any process involving solvent displacement or solvent removal. A high-strength resin composition or molded body prepared by using the cellulose nanofiber is also provided. In refining cellulose in the presence of a compound having a reactive double bond and a hydroxyl value of 200 KOHmg/g or more, the cellulose has a moisture content of 4 to 25 parts by mass with respect to 100 parts by mass of the amount of the cellulose converted on the assumption that the percentage moisture of the cellulose is 0%.
