PROBLEM TO BE SOLVED: To provide a polypropylene resin foam sheet in which there is rigidity, and a surface is flexible; a production method of the same; and a partition plate.SOLUTION: A polypropylene resin foam sheet comprises a monolayer sheet extruded from a porous die, in which a resin component is a non-crosslinked polypropylene resin, and satisfies any of the following (a)-(c), a production method of the same and a partition plate are disclosed. (a) An ethylene component amount in the non-crosslinked polypropylene resin is 10-20 mass%, (b) a loss tangent of the non- crosslinked polypropylene resin at 190°C, 0.02 rad/s is 0.8-2.0, (c) a bulk density is 0.06-0.12 g/cm. |
