<p>An object is to provide a resin foam sheet having good reformability, and a method for easily producing such a resin foam sheet. Provided are a resin foam sheet formed by extrusion foaming with an extruder a polypropylene-based resin composition mainly composed of a polypropylene-based resin component containing a polypropylene-based resin and a high melt tension polypropylene resin having a higher melt tension than that of the polypropylene-based resin, wherein the high melt tension polypropylene resin has a melt tension after being passed through the extruder of 4 cN or more and 10 cN or less, and a rate at breakage after being passed through the extruder of 12 m/min or higher and 26 m/min or lower, and the like.</p> |
