PURPOSE: To obtain a polypropylene resin composition comprising a specific propylene polymer and a specific fatty acid amide, hardly generating odor and excellent in heat resistance and sliding property. CONSTITUTION: This composition comprises (A) 100 pts.wt. propylene polymer having 0.01-1000g/10min melt flow rate(MFR) measured according to ASTM D-1238, in which the heat of fusion (ΔHm) obtained from measurement of differential scanning calorimeter(DSC) and the MFR satisfy formula I and (B) 0.01-1 pt.wt. N-substituted type fatty acid amide of formula II (R<1> and R<2> are each an 11-21C alkyl or an alkenyl) (preferably N-stearyl erucic acid amide). The component A is preferably obtained by polymerizing propylene using a catalyst obtained by bringing a solid component consisting essentially of Mg, Ti, a halogen and an electron donating compound into contact with an olefin in the presence of an organoaluminum compound and an organosilicon compound of formula III (R<3> is an N-containing heterocyclic substituent group, etc.; R<4> is a 1-10C hydrocarbon, etc.; R<5> is CH3 , etc.) and combining the resultant catalyst component with an organometallic compound.
