A resin powder containing an ultraviolet scattering agent (such as a titanium oxide particle or a zinc oxide particle) is deformed into a plate-like form. The ultraviolet scattering agent may include, for example, a titanium oxide particle or zinc oxide particle having an average particle diameter of not more than 100 nm. A resin contained in the resin powder may particularly be a thermoplastic resin (e.g., a polyamide resin). The plate-like resin powder may be a powder obtainable by deforming resin particles, each containing the ultraviolet scattering agent, into a plate-like form. The resulting resin powder has an excellent ultraviolet scattering function.
