Abstract
A laminated foam sheet includes a foam layer, a first non-foam layer positioned on one side of the foam layer, and a second non-foam layer positioned on another side of the foam layer, in which the foam layer includes a polyolefin-based resin, the foam layer has a thickness of 2.0 to 6.0 mm, the foam layer has a closed cell ratio of 70% or more, the first non-foam layer includes a non-cross-linked olefin-based elastomer, the first non-foam layer has a maximum static friction coefficient determined by JIS K7125 of 2.0 or more, the second non-foam layer has a maximum static friction coefficient determined by JIS K7125 of 1.0 or less, and a ratio represented by [basis weight of first non-foam layer (a)]/[basis weight of second non-foam layer (b)] is 0.5 to 2.0.
