To provide a fireproof sheet having high deformation capability and a thermal expansion member, etc. using the fireproof sheet.SOLUTION: A fireproof sheet 1 is primarily comprised of face materials 5, a thermal expansion member 3, etc. The fireproof sheet 1 is configured by forming the thermal expansion member 3 between a pair of face materials 5. The thermal expansion member 3 is, for example, a putty sheet-like, rubber sheet-like or mat-like member, or a sponge-like or porous member made of a powder-like material. Namely, the thermal expansion member 3 has flexibility. Accordingly, the fireproof sheet 1 including the face material 5 has the flexibility as a whole. One surface of the thermal expansion member 3 includes projections 7 and recesses 9 formed thereon. In other words, at least one surface of the thermal expansion member 3 is formed into a corrugated surface.SELECTED DRAWING: Figure 1 【課題】 変形能力が高い耐火シート及びこれを用いた熱膨張部材等を提供する。【解決手段】 防火シート１は、主に、面材５、熱膨張部材３等から構成される。防火シート１は、一対の面材５の間に、熱膨張部材３が形成されて構成される。熱膨張部材３は、例えばパテシート状、ゴムシート状、マット状の部材又はパウダー状の素材から作られたスポンジ状や多孔質状の部材である。すなわち、熱膨張部材３は可撓性を有する。このため、面材５を含めた防火シート１は、全体として可撓性を有する。熱膨張部材３の一方の面には、凸部７と凹部９が形成される。すなわち、熱膨張部材３の少なくとも一方の面が凹凸状に形成される。【選択図】図１
