Title:
LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2021/153589
Kind Code:
A1
Abstract:
A laminated glass (1) according to an embodiment of the present invention is provided with: a first glass plate (11); a second glass plate (12); and an intermediate film (13) held between the first glass plate (11) and the second glass plate (12). Reflection coefficients Γ1 and Γ2 satisfy 0.0 ≦ Γ1 ≦ 0.2 and 0.0 ≦ Γ2 ≦ 0.2, respectively, where a prescribed frequency at 60 GHz to 100 GHz is F[GHz], a specific inductive capacity of the first glass plate is εg1, a specific inductive capacity of the second glass plate is εg2, and a specific inductive capacity of a first intermediate film provided in a first region of the intermediate film is εm1 at the frequency F, and the reflection coefficient at an interface between the first glass plate and the first intermediate film is Γ1 and the reflection coefficient at an interface between the second glass plate and the first intermediate film is Γ2 during incidence at the frequency F.
