Abstract

A resin composition may contain a compound including phosphorus and sulfur as constituent elements and having a disulfide bond, and a thermoplastic resin. The first compound may have a peak observed by Raman spectroscopy derived from a disulfide bond which bonds two phosphorus elements. The thermoplastic resin may be a styrene-butadiene-based thermoplastic elastomer, a cellulose ether, a carboxymethylcellulose, a fluorine-based resin, a polyether, a polyacrylonitrile, a polyvinylacetate, a polymethyl methacrylate, a polyphosphazene, a polyvinylpyrrolidone, a polyethylene oxide, a polyacrylic acid, and/or a polyamideimide resin.
