Abstract

A resin composition includes a cellulose acylate (A); and an aromatic compound (B) not containing a functional group that reacts with the cellulose acylate (A), but containing a long-chain aliphatic group and at least one of a phenolic hydroxy group and a monoglycidyl ether group directly bonded to an aromatic group of the aromatic compound (B), in which a mass ratio (B)/(A) of the aromatic compound (B) to the cellulose acylate (A) is 0.15 or more.
