Zusammenfassung: | To provide a heat insulation film having high heat insulation property, and excellent adhesion to a substrate.SOLUTION: A heat insulation film is formed on a substrate. The heat insulation film is constituted of a porous body containing glass and inorganic fibers. In the heat insulation film, a dispersion part, and a plurality of coagulation parts scattered in the dispersion part, exist. The coagulation parts are parts in which a fiber ratio X which is a ratio of an area occupied by the inorganic fibers is 35% or more and 60% or less. The dispersion part is a part in which the fiber ratio X is less than 35% and exceeding 60%.SELECTED DRAWING: Figure 1
【課題】遮熱性が高く、基材に対する密着性が良好である遮熱膜を提供すること。【解決手段】遮熱膜は基材上に形成される。前記遮熱膜は、ガラス及び無機繊維を含む多孔質体により構成される。前記遮熱膜には、分散部と、前記分散部の中に点在する複数の凝集部とが存在する。前記凝集部は、前記無機繊維が占める面積の割合である繊維割合Xが35%以上60%以下である部分である。前記分散部は、前記繊維割合Xが35%未満又は60%を超える部分である。【選択図】図1 |
