Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a propylene resin material capable of providing a molded body excellent in impact property, tensile property and exterior appearance, and to provide a manufacturing method thereof.SOLUTION: A propylene resin material contains a propylene single polymer part (I) and a propylene-ethylene copolymer part (II) and satisfies following requirements and has an addition average calculated by a specific method of 20% or less and the content of components insoluble in boiling xylene of 4 wt.% or less. Requirements: A value calculated by a formula:(C2'CXIS/C2'CXS)×100 from the content of a structural unit derived from ethylene contained in a xylene-soluble component of the propylene resin material at 20°C (C2'CXS) and the content of a structural unit derived from ethylene contained in a xylene-insoluble component of the propylene resin material at 20°C (C2'CXIS) is 100 or more.
