PROBLEM TO BE SOLVED: To provide a laminated foam sheet that can further improve the appearance of a container and printing characteristics.SOLUTION: A laminated foam sheet comprises: a foam layer 10 formed by foaming a thermoplastic resin containing a foaming agent; and a non-foamed layer 20 made of a thermoplastic resin and provided on at least one surface of the foam layer 10. A region in the foam layer 10 from a boundary 22 between the foam layer 10 and the non-foamed layer 20 to a depth of 30 μm has a content of the foaming agent of 0.010-0.100 g/cm. Preferably, a region in the foam layer 10 from the boundary 22 between the foam layer 10 and the non-foamed layer 20 to a depth of 200 μm includes bubbles in an amount of 100-1,000 bubbles/mm. |
