Abstract
There are provided a resin composition that is suitable for the production of a flame-retardant molded article and that can provide high flame retardancy even with a small amount of flame retardant added, and a flame retardancy determination method for determining the flame retardancy of a resin composition. The resin composition of the present invention contains a thermoplastic resin, a cellulosic material, and a phosphate flame retardant and satisfies relational expressions (1) and (2) (where in expressions (1) and (2), T, T, and Tare temperatures at weight loss rate peaks in thermogravimetric analysis, Tis a temperature (° C.) at a weight loss rate peak of the thermoplastic resin, Tis a temperature (° C.) at a weight loss rate peak of the cellulosic material, and Tis a temperature (° C.) at a weight loss rate peak of the resin composition. When the resin composition has two weight loss rate peaks, Tis a temperature at a peak on a lower temperature side).
