PROBLEM TO BE SOLVED: To provide flame retardant polymeric composite materials which are inexpensive and exhibit high flame retardance, compositions for making the same, and molded products constituted of the flame retardant polymeric composite materials. SOLUTION: Flame retardance imparted composite particles 10 having a structure in which a carrier material particle 1 composed of one or more of a polymeric material, an inorganic material, and a metallic material has been compounded with a compound layer 2 containing a silicon component and/or a metallic component and oxygen are dispersed in and/or coated on a substrate (i.e., a target material to be imparted with flame retardance) composed of a polymeric material such as a resin to fix them on the surface of the substrate and, e.g. when intense heat is given to the target material, the compound layer of the flame retardance imparting composite particles forms a protective film by the intense heat to inhibit combustion. The effect of formation of the protective film can impart high flame retardant performance which, specifically, meets the range of V-0 to V-2 according to the UL 94 flammability test to the target material.
