Abstract
Provided is a multilayer foam sheet excellent in flexibility and mechanical strength in the shear direction. A multilayer foam sheet of the present invention is a multilayer foam sheet including: a base layer including a foam layer, and a surface layer including a foam layer or a resin film and laminated on at least one side of the base layer directly or with another layer interposed therebetween, a low-speed shear modulus being 50 MPa or more, and a 25% compressive strength being 125 kPa or less.
