HEAT INSULATION MEMBER
To provide a heat insulation member which is used while being held between objects, has a high mechanical strength and is improved in a heat insulation performance between the objects.SOLUTION: A heat insulation member (16) comprises: a first principal surface (161) which faces one object when the heat insulation member is held between objects; and a second principal surface (162) which is positioned at an opposite side of the first principal surface (161) and faces the other object. The heat insulation member (16) has a porous structure of ceramic including pores, and a skeleton of the porous structure is formed from ZrOparticles and a dissimilar material being present on surfaces of ZrOparticles. The dissimilar material includes at least one selected from among SiO, TiO, LaOand YO. The dissimilar material is present on the surfaces of ZrOparticles, in particular, in a connection part between particles, thereby obtaining an excellent heat insulation performance while keeping a mechanical strength of the heat insulation member (16) high.SELECTED DRAWING: Figure 1
【課題】対象物間に挟まれて使用される高い機械的強度を有し、かつ、対象物間の断熱性能に優れた断熱部材を提供する。【解決手段】断熱部材（１６）は、対象物に挟まれた場合に一方の対象物に対向する第１主面（１６１）と、第１主面（１６１）とは反対側に位置し、他の対象物に対向する第２主面（１６２）とを備える。断熱部材（１６）は、気孔を有するセラミックの多孔質構造を有し、ＺｒＯ２粒子、および、ＺｒＯ２粒子の表面に存在する異種材料が、多孔質構造の骨格を形成する。異種材料は、ＳｉＯ２、ＴｉＯ２、Ｌａ２Ｏ３およびＹ２Ｏ３から選択された少なくとも１つを含む。異種材料がＺｒＯ２粒子の表面、特に、粒子間の接続部に存在することにより、断熱部材（１６）の機械的強度を高く維持しつつ、優れた断熱性能が得られる。【選択図】図１
