An object of the present invention is to provide a β-1,3-glucan derivative which is a polymer having β-1,3-glucan as a main chain, and has thermoplasticity and excellent moldability, and a preparation method thereof. That is, the present invention provides a β-1,3-glucan derivative having a structure represented by General Formula (1) as a main chain. n n n n n n n n n n (In Formula (1), each of a plurality of R 1 s independently represents a hydrogen atom or —COR 2 , n represents an integer of 1 or greater, and R 2 represents an aliphatic hydrocarbon group or an aromatic hydrocarbon group. In Formula (1), a plurality of the R 1 s may be the same as or different from each other, and at least a part of a plurality of the R 1 s is —COR 2 .) |
