Summary: | To provide a heat transfer suppression sheet that can suppress excessive outward bulging of end faces parallel to a thickness direction even when an elastic sheet is pressed in its thickness direction, and can suppress a decrease in heat insulation due to a reduction in thickness.SOLUTION: A heat transfer suppression sheet 10 includes: an elastic sheet 11 having a pair of main surfaces 11a perpendicular to the thickness direction and end surfaces 11b substantially parallel to the thickness direction; and an expansion suppression sheet 12 disposed continuously along at least the end surfaces 11b. The tensile strength of the expansion suppression sheet 12 is preferably 20 MPa or more and 150 MPa or less.SELECTED DRAWING: Figure 1
【課題】弾性シートがその厚さ方向に押圧された場合であっても、厚さ方向に平行な端面が外方に過度に膨出することを抑制することができるとともに、厚さの減少による断熱性の低下を抑制することができる熱伝達抑制シートを提供する。【解決手段】熱伝達抑制シート10は、厚さ方向に直交する一対の主面11a及び厚さ方向に略平行な端面11bを有する弾性シート11と、少なくとも端面11bに沿って連続して配置された膨出抑制シート12と、を有する。膨出抑制シート12の引張強度は20MPa以上であり、150MPa以下であることが好ましい。【選択図】図1 |
