PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass which causes little remaining of air bubbles between a laminated glass member and an intermediate film when laminated glass is obtained.SOLUTION: An intermediate film for laminated glass contains a thermoplastic resin, has a portion of which an increment of a thickness from one end to the other end increases in a region of which a thickness increases, has a portion of which the increment of the thickness from the one end to the other end decreases in the region of which the thickness increases, has a portion of which a wedge angle increases from the one end to the other end increases in a region of which a cross-sectional shape in a thickness direction has a wedge shape, or has a portion of which a wedge angle increases from the one end to the other end decreases in the region of which the cross-sectional shape in the thickness direction has the wedge shape, where surface ten-point average roughness Rz in the central position at the portion of which the increment of the thickness increases, the portion of which the increment of thickness decreases, the portion of which the wedge angle increases or the portion of which the wedge angle decreases is 20 μm or more.SELECTED DRAWING: Figure 1

    【課題】合わせガラスを得たときに、合わせガラス部材と中間膜との間に気泡を残存し難くす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、熱可塑性樹脂を含み、厚みが増加している領域の中に、一端から他端にかけて厚みの増加量が大きくなる部分を有するか、厚みが増加している領域の中に、一端から他端にかけて厚みの増加量が小さくなる部分を有するか、厚み方向の断面形状が楔状である領域の中に、一端から他端にかけて楔角が大きくなる部分を有するか、又は、厚み方向の断面形状が楔状である領域の中に、一端から他端にかけて楔角が小さくなる部分を有し、前記厚みの増加量が大きくなる部分、前記厚みの増加量が小さくなる部分、前記楔角が大きくなる部分、又は前記楔角が小さくなる部分の中央の位置における表面の十点平均粗さRzが20μm以上である。【選択図】図1
