Provided is a foam sheet having excellent impact-absorption properties and having excellent resistance to repeated impacts. This foam sheet is characterized in that the average cell diameter is 10 to 200 μm, the push-back force when the thickness has been compressed by 50% is 6.0 N/cm 2 or less, and the thickness recovery rate, defined in the formula below, is 90% or greater.nnThickness recovery rate (%) = (thickness at 0.5 seconds after release from compressed state)/(initial thickness) × 100nInitial thickness: thickness of foam sheet prior to applying a loadnThickness at 0.5 seconds after release from compressed state: thickness of foam sheet after the foam sheet is maintained for 120 seconds in a state where a load of 100 g/cm 2 is applied thereon, the compression is released, and then 0.5 seconds has elapsed from the release |
