A shock-absorbing sheet comprises a foamed resin layer having a thickness of 200 &#x3bc;m or less, a void ratio (P) of a plane directional cross section at a thickness of 0.1 T, a void ratio (P) of a plane directional cross section at a thickness of 0.5 T, and a void ratio (P) of a plane directional cross section at a thickness of 0.9 T from one surface of the foamed resin layer each ranging from 10 to 70 area %; and the standard deviation (P&#x3c3;) for an average void ratio found from the void ratio (P), the void ratio (P) and the void ratio (P) ranging from 1.0 to 20.

Shock-absorbing sheet

A heat-conducting sheet according to the present invention is a heat-conducting sheet having an initial Asker C hardness of 50 or less, the heat-conducting sheet containing an elastomer resin at the volume proportion of 30 to 70%, and a thermally conductive filler at the volume proportion of 30 to 70%, in which the elastomer resin has a viscosity at 25&#xb0; C. of 3000 Pa&#xb7;s or less, and the elastomer resin has a lamella length of 20 mm or more. According to the present invention, a heat-conducting sheet which has initial flexibility sufficient to exhibit excellent shape conformability and in which residual stress is reduced after compression by applying pressure can be provided.
