PROBLEM TO BE SOLVED: To provide a laminated glass that can improve sound insulation property, particularly against sounds at high frequencies greater than 5000 Hz.SOLUTION: The laminated glass includes an outside glass plate 1, an inside glass plate 2 disposed to oppose to the outside glass plate 2, and an intermediate film 3 held between the outside glass plate 1 and the inside glass plate 2. The intermediate film 3 includes a core layer 31, at least one outer layer 32 disposed on at least the outside glass plate 1 side, selected between the outside glass plate 1 side and the inside glass plate 2 side sandwiching the core layer 31. At least one of the outer layers 32 has a Young's modulus of 560 MPa or more at a frequency of 100 Hz at a temperature of 20°C.SELECTED DRAWING: Figure 1 |
