A shock-absorbing sheet comprises a foamed resin layer having a thickness of 200 µm or less, a void ratio (P 0.1 ) of a plane directional cross section at a thickness of 0.1T, a void ratio (P 0.5 ) of a plane directional cross section at a thickness of 0.5T, and a void ratio (P 0.9 ) of a plane directional cross section at a thickness of 0.9T from one surface of the foamed resin layer each ranging from 10 to 70 area%; and the standard deviation (Pσ) for an average void ratio found from the void ratio (P 0.1 ), the void ratio (P 0.5 ) and the void ratio (P 0.9 ) ranging from 1.0 to 20. |
