Provided is a polypropylene composition which is a molding material having good flexibility and good elastic recovery. The polypropylene composition comprises from 1 to 99% by weight of elastomeric polypropylene obtained through (co)polymerization of propylene or propylene and olefin except propylene in the presence of a metallocene catalyst (A) that comprises a metallocene compound (A), an activator compound and optionally an organoaluminum compound, or of a supported metallocene catalyst (A) that comprises the metallocene catalyst (A) supported on a particulate carrier, or of a catalyst that comprises tetraneophyl zirconium supported on alumina, and from 1 to 99% by weight of atactic polypropylene totaling 100% by weight.
