To provide a propylenic resin composition for medical treatments, satisfying the test requirements of 1, polyethylene or polypropylene aqueous parenteral injection containers in the plastic medicine container test method, and holding excellent heat resistance, rigidity, injection moldability, and transparency, and to provide its molded article.

This propylenic resin composition for the medical treatments comprises 60-99 pts.wt. of a propylenic (co)polymer comprising propylene homopolymer or a propylenic copolymer comprising propylene and an -olefin in an amount of 1 wt.% and having a melt flow rate of 0.5-100 g/10 min, propylene-ethylene block copolymer obtained by sequentially polymerizing 30-95 wt.% of propylene homopolymer or propylene-ethylene random copolymer component (A) having an ethylene content of 7 wt.% in the first process and 70-5 wt.% of a special propylene-ethylene random copolymer component (B) containing ethylene in a larger amount by 3-20 wt.% than that of the component (A) in the second process in the presence of a metallocene catalyst, and 0.01-0.6 pt.wt. of a nucleating agent.
