Abstract: A foamed resin molded article (1) including: a foamed resin layer (30) comprising a first resin which is a copolymer including a rubber component, a vinyl cyanide monomer unit and an aromatic vinyl monomer unit, and a blowing agent; and a non-foamed resin layer (50) covering the foamed resin layer (30), wherein: the non-foamed resin layer (50) comprises a second resin which is a copolymer including a rubber component, a vinyl cyanide monomer unit, and an aromatic vinyl monomer unit; and the amount of the rubber component in the non-foamed resin layer (50), determined by pyrolysis-gas chromatography/mass spectrometry (PGC/MS), is 1% by mass or more and 30% by mass or less, based on the total mass of the second resin.
