<P>PROBLEM TO BE SOLVED: To provide a polypropylene resin composition being capable of providing a highly transparent and highly glossy releasing film having a low releasing strength. Ž<P>SOLUTION: A polypropylene resin composition for the releasing film obtained by performing melt kneading of an MFR adjuster with a polypropylene resin having an inherent viscosity of 2.2-5.0 (dl/g), is characterized in that the weight-average molecular weight measured by Gel Permeation Chromatography (GPC) is 2.8×10<SP>5</SP>to 6.5×10<SP>5</SP>, and the ratio of the distribution of the molecular weight of 2.64×10<SP>6</SP>or more is 2% or less in the molecular weight distribution measured by Gel Permeation Chromatography (GPC).
