Cellulose nanofibers have an average degree of polymerization of 600 or more to 30000 or less, an aspect ratio of 20 or more to 10000 or less, an average diameter of 1 nm or more to 800 nm or less, and an Ibeta-type crystal peak in an X-ray diffraction pattern, in which a hydroxyl group is chemically modified by a modifying group. |
