Abstract

Provided is a silicone foam sheet that expresses excellent bubble removability, that has satisfactory adhesiveness with an adherend and satisfactory sealability, that maintains the expression of these effects even when its thickness is reduced, that preferably expresses a stable modulus of elasticity over a region from a low-temperature region to a high-temperature region, and that suppresses both of its compression set in the low-temperature region and its compression set in the high-temperature region to low levels. Also provided is a method of producing such silicone foam sheet. The silicone foam sheet comprises an open-cell structure having a thickness of from 10 μm to 3,000 μm, wherein an open-cell ratio is 90% or more, an average cell diameter of the silicone foam sheet is from 1 μm to 50 μm, and 90% or more of all cells therein each has a cell diameter of 80 μm or less.
