Resin composition and resin molded article
A resin composition includes cellulose derivatives, wherein, in a molecular weight distribution curve obtained by subjecting the cellulose derivatives to gel permeation chromatography (GPC), a maximum (P L ) exists in a low molecular weight region of 10,000 to 40,000 and a maximum (P H ) exists in a high molecular weight region of 100,000 to 180,000, and with respect to a total amount of a peak area (S L ) of a peak including the maximum (P L ) and a peak area (S H ) of a peak including the maximum (P H ), a ratio of the peak area (S L ) is 1% to 99% and a ratio of the peak area (S H ) is from 1% to 99%.
