To provide a laminated foamed sheet having a slip-preventive surface and excellent thermal moldability and abrasion resistance and a molded body thereof.SOLUTION: A laminated foamed sheet includes a foamed layer 10 and a first non-foamed layer 20 positioned on one surface of the foamed layer 10. The foamed layer 10 has a closed cell ratio of 70% or more and the density of 50 to 1000 kg/m3. The maximum load required by JIS-K7125 of the first non-foamed layer 20 is 10 to 50 N. A ratio of a major diameter to a minor diameter in a region from an interface between the foamed layer 10 and the first non-foamed layer 20 to the depth, which is 15% of the thickness of the foamed layer 10, in a thickness direction of the foamed layer 10 is 4.0 or more and a ratio of bubbles is 50% or more.SELECTED DRAWING: Figure 1
