Abstract: Disclosed is a laminated substrate for a window, in which substrates are laminated through an intermediate layer structure, the laminated substrate includes a peripheral edge region, and a central region, wherein the intermediate layer structure includes a first region, and a second region, wherein, when a value obtained by dividing shear modulus of the second region against static force by shear modulus of the first region against the static force is denoted by x, a ratio of an area of the second region with respect to an area of the whole laminated substrate for the window is greater than or equal to (−74.87x+204.47)%, for 1.40≤x≤2.72; and greater than or equal to (−0.0067x+0.87)%, for x>2.72; and wherein a ratio of an area of the second region in the central region is less than or equal to 83%.
