There is provided a polypropylene resin composition comprising the following components (A) and (B): (A) 10 to 99% by weight of a propylene homopolymer produced by polymerization with a metallocene catalyst, which homopolymer satisfies the following requirements (a1) and (a2): (a1) its melting peak exists between 120° C. and 170° C. according to a differential scanning calorimetry (DSC), and (a2) its intrinsic viscosity [eta] is 0.5 to 6 dl/g, and (B) 90 to 1% by weight of an amorphous alpha-olefin polymer containing not less than 20% by mol of an alpha-olefin unit having 3 to 20 carbon atoms, which alpha-olefin polymer satisfies the following requirements (b1) to (b3): (b1) its melting peak does not exist substantially according to a differential scanning calorimetry (DSC), (b2) its intrinsic viscosity [eta] is 0.1 to 10 dl/g, and (b3) its molecular weight distribution is not more than 4, wherein a total of the components (A) and (B) is 100% by weight, and a total of all units contained in the amorphous alpha-olefin polymer is 100% by mol.
