PROBLEM TO BE SOLVED: To prepare a polypropylene-based resin foamed sheet having improved formability. SOLUTION: This polypropylene-based resin foamed sheet comprises a polypropylene-based resin and polytetrafluoroethylene, or a high melt-tension polypropylene-based resin and a polypropylene-based resin, and having a sheet density of 300 to 850 kgm-3 and a closed cell porosity of >=40%. The foamed sheet scarcely draws down, has excellent formability, and can be formed with conventional forming device.
