Provided are a resin molding material, a method for producing same, and a method for producing resin member or the like, said resin molding material being a resin molding material which is capable of reducing a loss of ultraviolet absorber, resulting in less contamination in facilities, minimizing the impact of harmful lights by efficiently absorbing harmful lights in the wavelength region of 380 to 400 nm (to 420 nm), and suppressing the absorption of lights having a wavelength of not shorter than 400 nm (420 nm) which is a primary cause of early-stage yellowing to thereby produce a member having a superior appearance since the ultraviolet absorber is less prone to be sublimed during hot-melt compounding (first/second processing) that requires a high-temperature processing, or during other heat processing. The resin molding material is used in heat processing and comprises a resin and a 2-phenylbenzotriazole derivative that contains a thioether-containing group.
