Abstract:
A laminated glass according to the present invention includes a first glass plate, a second glass plate, and an interlayer film. The interlayer film includes a laminated region including a first layer that is in contact with the first glass plate, a second layer that is in contact with the second glass plate, and a third layer disposed between the first layer and the second layer. When the relative dielectric constant of the first glass plate is denoted by εg1, the relative dielectric constant of the second glass plate is denoted by εg2, the relative dielectric constant of the first layer is denoted by εm1, the relative dielectric constant of the second layer is denoted by εm2, and the relative dielectric constant of the third layer is denoted by εm3, relationships εm1 εm1, εm3>εm2 are established.
