PROBLEM TO BE SOLVED: To provide a hollow molded body excellent in flexibility, heat resistance, kink resistance, transparency, strength, repeated extensibility, tube tackiness, and resistance to water, an alcohol and an acid, and to provide a laminated hollow molded body, a reinforced hollow molded body and a reinforced laminated hollow molded body using the hollow molded body. SOLUTION: The hollow molded body is made from a composition (X) comprising: (A) 1-95 pts.wt. of an isotactic polypropylene; (B) 5-99 pts.wt. of a flexible propylene polymer which has anα-olefin content of 0-30 mol% and has a melting point as measured by differential scanning calorimetry (DSC) of lower than 120°C or whose melting point is not observed (wherein the sum of (A) and (B) is defined as 100 pts.wt.); and optionally (C) 0-50 pts.wt. based on 100 pts.wt. of the sum of the components (A) and (B) of a flexible polymer having a Shore A hardness of 95 or less and/or a Shore hardness D of 60 or less, except for the flexible propylene polymer (B).
