Abstract: The multilayer foam sheet includes a polyethylene resin foam layer and a resin layer laminated on at least one of the two surfaces of the foam layer. The resin layer has a multilayer structure formed from a surface layer and an intermediate layer. Both the surface layer and the intermediate layer contain a polyethylene resin and a polymeric antistatic agent. The polymeric antistatic agent is contained in the intermediate layer at a proportion of 30-70 wt % (inclusive). The polymeric antistatic agent is contained in the surface layer at a proportion of at least 5 wt % to less than 30 wt %.
