The invention provides a polypropylene preparation sheet and a manufacture method thereof and a secondary forming body (a container and the like) as well as a polypropylene composition adapted to manufacture the sheet. The polypropylene preparation sheet is transparent, rigid, resistant to heat, has uniformly extending performance and excellent resistance to impact at low temperature. Additionally, the polypropylene preparation sheet is easily formed by hot and extends in dual directions. The polypropylene composition of the invention is characterized by comprising a propylene polymer containing ethylene and a crystallization nucleating agent; when the ethylene content of the propylene polymer containing ethylene is less than 1 mass% and molecular weight distribution thereof (Mw/Mn) is 6-20, the amount of xylene insoluble components is above 96.5 mass% at 25 DEG C and below 99.5 mass%; additionally, the stereoregularity (mmmm) of the xylene insoluble components is from 97.5% to 99.5%;and the crystallization nucleating agent has below 0.18 mass fraction with respect to an ethylene-containing propylene polymer having 100 mass fractions and the melt flow rate of the crystallization nucleating agent is 1g/10 minutes-15g/10minutes.
