A polypropylene resin in-mold foam molded article that has a volume resistivity value of 10©€¢cm or more and 5,000©€¢cm or less and is produced from polypropylene resin foamed particles including a polypropylene resin composition containing 11 parts by weight or more and 25 parts by weight or less of an electroconductive carbon black having a DBP absorption amount of 300 cm 3 /100 g or more and 600 cm 3 /100 g or less and 3 parts by weight or more and 15 parts by weight or less of melamine cyanurate relative to 100 parts by weight of a polypropylene resin has a low open-cell ratio, excellent electric conductivity, and excellent flame retardancy. In particular, a polypropylene resin in-mold foam molded article that is produced from polypropylene resin foamed particles containing an inorganic foaming agent and conventionally having low flame retardancy exhibits excellent flame retardancy. |
