Abstract

A laminated glass according to an embodiment of the present invention includes a first glass plate, a second glass plate, and an interlayer film held between the first glass plate and the second glass plate. When a relative dielectric constant of the first glass plate is represented by ε; a relative dielectric constant of the second glass plate is represented by ε; a relative dielectric constant of a first interlayer film provided in a first region of the interlayer film is represented by ε; a reflection coefficient at an interface between the first glass plate and the first interlayer film is represented by Γ; and a reflection coefficient at an interface between the second glass plate and the first interlayer film is represented by Γ, the reflection coefficients Γand Γsatisfy relations 0.0≤Γ≤0.2 and 0.0≤Γ≤0.2.
