PROBLEM TO BE SOLVED: To provide a molded item such as a film, a sheet, a tube, a hose, an injection-molded article or a laminated product that is improved in stickiness, the change in external appearance with time and the like resulting from a propylene-based soft resin and is excellent in the balance among transparency, flexibility, heat resistance and the like. SOLUTION: The molded item is composed of a resin composition that comprises a propylene-ethylene copolymer having an ethylene unit content of at most 20 mol% and an [EEE] triad chain fraction f<SB>EEE</SB>of at most 0.1 mol%, and gives fractionated components by the temperature-raising elution fractionation method (TREF) that satisfy the requirements below. The component 1 which is soluble at 0°C accounts for 10-80 mass%; the component 2 which is eluted at a temperature higher than 0°C and not higher than 70°C accounts for 10-60 mass%; the component 3 which is eluted at a temperature higher than 70°C and lower than 100°C accounts for 5-50 mass%; and the component 4 which is eluted at a temperature of 100°C or higher accounts for 0-30 mass%, provided that (the component 1)+(the component 2)+(the component 3)+(the component 4)=100 mass%.
