Provided is a polypropylene resin composition which is excellent in flexural modulus and impact strength and can reduce the amount of the resin used in case of the injection molding. The polypropylene resin composition comprises 5-100 parts by weight of a beta-nucleus forming agent master batch; and 0.03-0.1 parts by weight of calcium stearate based on 100 parts by weight of a polypropylene resin. Preferably, the polypropylene resin is a propylene-ethylene copolymer having a melt index of 10-15 g/10 min; the beta-nucleus forming agent master batch has an isotactic pentad fraction of 98% or more measured by NMR; and the beta-nucleus forming agent is pimelic acid.
