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 εg1; a relative dielectric constant of the second glass plate is represented by εg2; a relative dielectric constant of a first interlayer film provided in a first region of the interlayer film is represented by εm1; a reflection coefficient at an interface between the first glass plate and the first interlayer film is represented by Γ1; and a reflection coefficient at an interface between the second glass plate and the first interlayer film is represented by Γ2, the reflection coefficients Γ1 and Γ2 satisfy relations 0.0≤Γ1≤0.2 and 0.0≤Γ2≤0.2.
