To provide a heat diffusion sheet that shows reduced tendency to catch fire at high temperatures, while showing a reduced volumetric change.SOLUTION: A heat diffusion sheet comprises a first heat insulation layer, and a first heat transfer layer disposed on each side of the first heat insulation layer. The heat transfer rate of the first heat transfer layer in a plane direction is at least 10 times the heat transfer rate of the first heat insulation layer in the plane direction.SELECTED DRAWING: Figure 2 【課題】高温時に類焼を防止しつつ、体積変化を抑えた熱拡散シートを提供する。【解決手段】第一断熱層と、前記第一断熱層の両側にそれぞれ配置された第一伝熱層と、を備える、シート状の熱拡散シートであって、前記第一伝熱層の面方向への熱伝導率が、前記第一断熱層の面方向への熱伝導率の１０倍以上である。【選択図】図２
