HEAT INSULATION INTERIOR MEMBER, MANUFACTURING METHOD OF HEAT INSULATION INTERIOR MEMBER AND VEHICULAR CEILING MATERIAL HAVING HEAT INSULATION INTERIOR MEMBER

To provide a heat insulation interior member which can maintain the high heat insulation performance over a long period, is excellent in the productivity, handleability and reliability, is free from maintenance and is light-weight, and provide a manufacturing method of the heat insulation interior member and a vehicular ceiling material having the heat insulation interior member.SOLUTION: A heat insulation interior member 20 comprises: a first vacuum heat insulation material 27; a second vacuum heat insulation material; and a foamed body 23. The first vacuum heat insulation material 27 and the second vacuum heat insulation material are sealed in an outer bag in a decompressed manner such that a core material molded body molded with a core material including an inorganic powder body is surrounded by the outer bag. The foamed body is integrally laminated so as to cover the first vacuum heat insulation material 27 and the second vacuum heat insulation material.SELECTED DRAWING: Figure 3 【課題】長期に渡り高い断熱性能を維持でき、生産性、取扱い性、信頼性に優れ、メンテナンス不要でかつ軽量な断熱内装部材、断熱内装部材の製造方法及び断熱内装部材を備えた車両用天井材を提供する。【解決手段】断熱内装部材２０は、第１真空断熱材２７と、第２真空断熱材と、及び発泡体２３と、を備える。第１真空断熱材２７及び第２真空断熱材は、無機系粉体を含む芯材が成形された芯材成形体が外袋で囲われ、外袋の内部に減圧封入されている。発泡体は、第１真空断熱材２７及び第２真空断熱材を覆うように一体に積層されている。【選択図】図３
