To provide a glass laminate capable of achieving both of heat shielding and infrared transparency in a region in which an information device transmits and/or receives infrared light.SOLUTION: A vehicle glass laminate including a pair of glass plates and an intermediate film positioned between the pair of glass plates includes a see-through region. In the condition that in the see-through region, a region satisfying at least one of T905≥90% and T1550≥80% is defined to be an infrared high transmissive region, the glass laminate is attached to a vehicle, the vehicle is arranged on a horizontal plane, and a straight line horizontal to the vehicle and passing through a point at a lower end in the infrared high transmission region in a plan view is defined to be a straight line P; the see-through region includes a first region existing on the glass laminate above a curve formed by projecting the straight line P onto the glass laminate in the normal direction of the glass laminate at the point of the lower end, and a second region existing below the curve. A proportion of the infrared high transmission region in the first region is 5% or more.SELECTED DRAWING: Figure 1
【課題】遮熱性と情報デバイスが赤外光を送信及び/又は受信する領域の赤外線透過性とを両立した合わせガラスを提供する。【解決手段】本合わせガラスは、一対のガラス板と、前記一対のガラス板の間に位置する中間膜と、を有する車両用の合わせガラスであって、透視領域を備え、前記透視領域において、T905≧90%、T1550≧80%の少なくとも一方を満たす領域を赤外高透過領域とし、前記合わせガラスを車両に取り付けて車両を水平面に配置したときに、平面視において、前記赤外高透過領域の下端の点を通り前記車両に水平な直線を直線Pとしたとき、前記透視領域は、前記直線Pを前記下端の点における前記合わせガラスの法線方向に対して前記合わせガラスに投影した曲線よりも前記合わせガラスの上方である第1領域と、前記曲線よりも下方である第2領域と、を含み、前記第1領域における前記赤外高透過領域の割合が5%以上である。【選択図】図1
