本发明提供一种在得到夹层玻璃时夹层玻璃部件和中间膜之间不易残留气泡的夹层玻璃用中间膜。本发明涉及一种夹层玻璃用中间膜,其含有热塑性树脂,所述中间膜具有一端以及位于所述一端的相反侧且厚度比所述一端厚的另一端,所述中间膜具有从一端到另一端厚度增加的区域,或者,所述中间膜具有厚度方向上的截面形状为楔形的部分,所述中间膜在厚度增加的区域中具有从一端到另一端厚度的增加量变大的部分;或者,所述中间膜在厚度增加的区域中具有从一端到另一端厚度的增加量减小的部分;或者,所述中间膜在厚度方向上的截面形状为楔形的区域中具有从一端到另一端楔角变大的部分;或者,所述中间膜在厚度方向上的截面形状为楔形的区域中具有从一端到另一端楔角变小的部分,所述厚度的增加量变大的部分、所述厚度的增加量变小的部分、所述楔角变大的部分、或者所述楔角变小的部分的中央位置的表面的十点平均粗糙度Rz为20μm以上。

    There is provided an interlayer film for laminated glass with which an air bubble can be made difficult to be left behind between a lamination glass member and the interlayer film when laminated glass is obtained. The interlayer film for laminated glass according to the present invention contains a thermoplastic resin and has a portion where the amount of increase in the thickness is increased in a direction from one end to the other end in the region where the thickness is increased, has a portion where the amount of increase in the thickness is decreased in a direction from one end to the other end in the region where the thickness is increased, has a portion where the wedge angle is increased in a direction from one end to the other end in the region where the sectional shape in the thickness direction is a wedge-like shape, or has a portion where the wedge angle is decreased in a direction from one end to the other end in the region where the sectional shape in the thickness direction is a wedge-like shape, and the ten-point average roughness Rz of the surface at a center position of the portion where the amount of increase in the thickness is increased, the portion where the amount of increase in the thickness is decreased, the portion where the wedge angle is increased, or the portion where the wedge angle is decreased is 20 µm or more.
