Abstract: A resin formed body obtained from a resin composition that contains a polypropylene resin and a cellulose fiber, the polypropylene resin partially containing an acid modified polypropylene resin,



wherein the resin formed body has a diffraction peak derived from a polypropylene α-crystal (040) plane at a position of a scattering vector s of 1.92±0.1 nm−1, a diffraction peak derived from a polypropylene β-crystal (300) plane at a position of a scattering vector s of 1.83±0.1 nm−1, and a diffraction peak derived from a cellulose Iβ type crystal (004) plane at a position of a scattering vector s of 3.86±0.1 nm−1, observed in a wide-angle X-ray diffraction measurement, and
wherein an orientation degree of the cellulose fiber in the resin formed body is larger than 0.1 and less than 0.8.
