PROBLEM TO BE SOLVED: To provide a foamed molded article without damaging the characteristics of the polypropylene-based resin composition, reducing vaporizable organic compound in the resin composition and excellent in light weight and rigidity because of having a high expansion rate. SOLUTION: This polypropylene-based resin foaming injection-molded article consisting of a modified polypropylene resin showing≥0.1 g/10 min and <50 g/10 min melt flow rate,≥2 cN melt tension and a strain hardening property is provided by having≤700μg/m<SP>3</SP>total evaporating concentration of toluene, xylene and ethylbenzene among vaporizable organic compounds released from the polypropylene-based resin foaming injection-molded article.
