PROBLEM TO BE SOLVED: To provide a propylene polymer composition produced in the presence of a metallocene catalyst and having a high melting point, a high crystallization temperature and excellent transparency. SOLUTION: The propylene polymer composition comprising (A) 100 mol.wt. of the propylenic polymer having a position-irregular unit rate P of 0.05 to 1.30 mol.% based on propylene 2,1-insertion for positioning the methyl groups at the adjacent positions, and (B) 0.15 to 2.0 mol.wt. of a sorbitol-based nucleating agent.
