PROBLEM TO BE SOLVED: To provide an expanded hollow molded product that expands uniformly, has a high expansion ratio, is lightweight, has high heat insulating property, and excels in stiffness property and heat resistance. SOLUTION: The expanded hollow molded product, which has the high expansion ratio, is lightweight and excels in heat insulating property, is obtained by using an ethylene polymer having excellent balance between a melt tension and a maximum melt stretch ratio as a main component. The expanded hollow molded product also excellent in draw-down resistance is obtained by using a composition where the ethylene polymer is combined with low density polyethylene.
