Abstract: There is provided a foamed sheet which takes only a short time to recover the thickness thereof after being compressed, and even if being subjected to repeated impacts, hardly decreases in the impact absorption. The foamed sheet according to the present invention comprises a foamed body formed of a resin composition comprising: a thermoplastic resin a and a silicone-based compound b having not more than 2,000 siloxane bonds; and/or a thermoplastic resin a′ having a silicone chain having not more than 2,000 siloxane bonds. The thermoplastic resin a is preferably at least one selected from the group consisting of acrylic polymers, rubbers, urethanic polymers and ethylene-vinyl acetate copolymers. The silicone-based compound b is preferably at least one selected from the group consisting of silicone oils, modified silicone oils and silicone resins.
