To provide a cushioning element which shows excellent cushioning performance with light-weight and excellent workability, and is suitable, for example, for a floor in a place of a weight lifting meet.

A sheet plate 5A made of a foam material 5 having the initial hardness of ASKER C 30-85 and apparent specific gravity of 0.30-0.70 is provided with a large number of through holes 5B thereon and a protective layer at least on the outside surface side thereof. Because the sheet plate 5A made of the foam material shows high cushioning performance against the impact energy, and further a large number of the through holes 5B are provided over the whole area thereof; the foam material is compressibly deformed by the vibratory impact load, and the impact energy can quickly be absorbed and dissipated. Further, because the sheet plate itself is light-weight, for example, the floor in the place of the weight lifting meet can be light-weighted and constructed with excellent workability.
