To the polypropylene resin 100 weight parts, DBP absorption amount of 300 cm 3/100 g or more 600 cm 3/100 g or less of the conductive carbon black 11 parts by weight or more 25 parts by weight, and the melamine cyanurate 3 parts by weight or more 15 wt part consists of polypropylene resin foam particles made of polypropylene-based resin composition comprising the following, polypropylene-based resin type in the molded foam volume resistivity is less than or equal to 10Ω · cm or more 5000Ω · cm has a low continuous air bubble rate , together with excellent conductivity, excellent flame retardancy. In particular, the polypropylene resin-mold foamed molded product prior flame retardant is prepared from polypropylene resin foamed beads with low was inorganic foaming agent, exhibits excellent flame retardancy.
