PROBLEM TO BE SOLVED: To provide an interlayer for glass laminate capable of enhancing rigidity of a glass laminate and enhancing acoustic insulation of the glass laminate.SOLUTION: The interlayer for glass laminate has a first layer and a second layer containing a polyvinyl acetal resin and a plasticizer, the first layer contains a filler, and average of a major axis of 100 aggregates of the filler in the order of larger with the major axis is 10 μm or less when there are 100 or more aggregates of the filler on a divided cross section of an area of 2 mmor average of the major axis of all aggregates of the filler when there is 99 or less aggregated of the filler on the divided cross section of the area of 2 mmis 10 μm or less when the area of total 2 mmof the divided cross section by dividing equally the first later into 101 in a length direction and collecting 100 exposed divided cross sections is observed at 1000 magnification by a scanning electron microscope.SELECTED DRAWING: Figure 1
【課題】合わせガラスの剛性を高めることができ、かつ合わせガラスの遮音性を高めることができる合わせガラス用中間膜を提供する。【解決手段】本発明に係る合わせガラス用中間膜は、ポリビニルアセタール樹脂と可塑剤とを含む第1の層及び第2の層を備え、前記第1の層が、フィラーを含み、前記第1の層を長さ方向にて101個に等分割して、露出した100個の分割断面をあわせた分割断面の合計2mm2の領域を走査型電子顕微鏡にて倍率1000倍で観察したときに、2mm2の領域の分割断面でのフィラーの凝集体が100個以上である場合に、長径が大きい順に100個のフィラーの凝集体の長径の平均値が10μm以下であるか、又は、2mm2の領域の分割断面でのフィラーの凝集体が99個以下である場合は、全数のフィラ−の凝集体の長径の平均値が10μm以下である。【選択図】図1
