PROBLEM TO BE SOLVED: To provide an ethylene/α-olefin copolymer composition capable of improving the rigidity, especially elongation at a tensile break point and impact strength at a low temperature, of a polypropylene resin, when the copolymer composition is used as a modifier, and excellent in productivity and operability not to cause problems such as blocking, during its use as a modifier, and to provide a polypropylene resin composition containing the ethylene/α-olefin copolymer composition. SOLUTION: A composition (i) comprising 30-70 wt.% specific ethylene/α- olefin copolymer [A], 1-69 wt.% specific ethylene/α-olefin copolymer [B], and 1-69 wt.% specific ethylene/α-olefin copolymer [C], a composition (ii) obtainable by cross linking the copolymer [A], [B], and [C], and a composition (iii) comprising a propylene copolymer (D) and the composition (ii) are provided.
