摘要：
A cellulose resin formed by substituting hydrogen atoms of hydroxy groups of a cellulose with a long-chain component being a linear saturated aliphatic acyl group having 14 or more carbon atoms and a short-chain component being an acyl group having 2 or 3 carbon atoms, in which a degree of substitution with the long-chain component (DSLo) and a degree of substitution with the short-chain component (DSSh) satisfy conditional expressions (1) and (2) shown below: DSLo+DSSh≥2.1 (1) 4≤DSSh/DSLo≤12 (2).
