To provide a ceiling member excellent in soundproofing property, especially in soundproofing property at high frequency, and also excellent in lightweight property.SOLUTION: A ceiling member is provided with: a spandrel 10 having a square main surface 11, side surfaces 13a and 13b erected toward the same surface side of the main surface 11 on opposite sides 12a and 12b of the main surface 11, a first engagement part 14a provided on one side surface 13a, and a second engagement part 14b having a shape engageable with the first engagement part 14a and provided on the other side surface 13b; and a laminate 20 disposed in a recessed part 15 formed by the main surface 11 and the side surfaces 12a and 12b and having a first face material 22 provided on the main surface 11 via a first adhesive layer 21 and a second face material 24 provided on the first face material 22 via a second adhesive layer 23. The area ratio of a region occupied by the first adhesive layer in the overlapping region of the main surface and the first face material is 5% or more and 95% or less, and the area ratio of a region occupied by the second adhesive layer in the overlapping region of the first face material and the second face material is 5% or more and 95% or less.SELECTED DRAWING: Figure 1
【課題】防音性、特に高周波数での防音性に優れており、かつ、軽量性にも優れた天井部材を提供する。【解決手段】四角形の主面１１を有し、主面１１の対向する辺１２ａ，１２ｂにおいて主面１１の同一面側に向かって側面１３ａ，１３ｂが立設され、一方の側面１３ａには第１係合部１４ａが設けられ、他方の側面１３ｂには第１係合部１４ａと係合可能な形状の第２係合部１４ｂが設けられているスパンドレル１０と、主面１１及び側面１２ａ，１２ｂによって形成される凹状部１５に配置され、主面１１に第１接着層２１を介して設けられる第１面材２２、及び、第１面材２２上に第２接着層２３を介して設けられる第２面材２４を有する積層体２０とを備え、主面及び第１面材の重複領域における第１接着層の占める領域の面積率は、５％以上９５％以下であり、第１面材及び第２面材の重複領域における第２接着層の占める領域の面積率は、５％以上９５％以下である。【選択図】図１
