PROBLEM TO BE SOLVED: To provide a glass laminate which allows attachment of apparatuses for a safety system, while achieving both weight saving and acoustic insulation, even when having a shading region.SOLUTION: A glass laminate includes an outer glass plate, an inner glass plate which is arranged so as to face the outer glass plate and is smaller in thickness than the outer glass plate, a first interlayer which is held between the outer and inner glass plates and is formed with a shading region 10 in a part and a through hole 30 in the shading region 10 and a second transparent interlayer arranged in the through hole 30. The thickness of the inner glass plate is 0.4-2.0 mm; the thickness of the outer glass plate is 1.8-2.3 mm; the first and second interlayers each consist of a plurality of layers including a rore layer; at least one of layers constituting the first interlayer is colored to form the shading region; and the Young moduli of the core layers of the first and second interlayers are 1-20 MPa at the frequency of 100 Hz and the temperature of 20°C, lower than Young moduli of other layers.

    【課題】軽量化と遮音性を両立しつつ、シェード領域を有していても、安全システム用の機器を取り付け可能な合せガラスを提供する。【解決手段】外側ガラス板と、外側ガラス板と対向配置され外側ガラス板よりも厚みが小さい内側ガラス板と、外側ガラス板及び内側ガラス板の間に挟持され着色されたシェード領域10が一部に形成されるとともにシェード領域10に貫通孔30が形成された第1中間膜と、貫通孔30に配置される透明の第2中間膜と、を備え、内側ガラス板の厚みを0.4〜2.0mm、外側ガラス板の厚みを1.8〜2.3mmとし、第1及び第2中間膜は少なくともコア層を含む複数の層で構成されており、第1中間膜を構成する層の少なくとも1つが着色されてシェード領域10を形成しており、第1及び第2中間膜のコア層のヤング率は周波数100Hz,温度20℃において1〜20MPaであり、他の層のヤング率よりも低い構成とする。【選択図】図1
