Claim 3:
4. The polypropylene film according to claim 1, wherein the polypropylene resin contains:
a linear polypropylene resin A having a difference of 8.0% or more attained by subtracting a differential distribution value when a logarithmic molecular weight Log (M)=6.0 from a differential distribution value when a logarithmic molecular weight Log (M)=4.5 in a molecular weight differential distribution curve;
a linear polypropylene resin B having a difference of less than 8.0% attained by subtracting a differential distribution value when a logarithmic molecular weight Log (M)=6.0 from a differential distribution value when a logarithmic molecular weight Log (M)=4.5 in a molecular weight differential distribution curve; and
a long-chain branched polypropylene resin C polymerized using a metallocene catalyst.
