| description | To provide a shock absorbing sheet having excellent peeling resistance and bending resistance at a low temperature.SOLUTION: A shock absorbing sheet includes a silicone-containing layer containing a silicone resin and an adhesive layer that overlaps the silicone-containing layer. A thickness of the silicone-containing layer is 60% or more and 95% or less of a thickness of the shock absorbing sheet. A storage elastic modulus (G1) at -20°C and a storage elastic modulus (G2) at 25°C of the silicone-containing layer are both 1×104 Pa or more and 1×105 Pa or less. The adhesive layer contains a resin (A) having a peak temperature of tangent loss of 0°C or lower.SELECTED DRAWING: Figure 1
【課題】低温下における剥離耐性及び耐屈曲性に共に優れる衝撃吸収シートを提供する。【解決手段】衝撃吸収シートは、シリコーン樹脂を含むシリコーン含有層と、前記シリコーン含有層に重なる粘着層とを備える。前記シリコーン含有層の厚みは、前記衝撃吸収シートの厚みの６０％以上９５％以下である。前記シリコーン含有層の－２０℃における貯蔵弾性率（Ｇ１）及び２５℃における貯蔵弾性率（Ｇ２）は、共に１×１０４Ｐａ以上１×１０５Ｐａ以下である。前記粘着層は、損失正接のピーク温度が０℃以下である樹脂（Ａ）を含む。【選択図】図１ |
