摘要： 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.

摘要： A filler disposition film that can use a commercially procurable filler material having good particle diameter uniformity, enables high positional precision of the filler disposition, can support even an increase in the surface area, and has a prescribed filler regularly disposed in a long resin film. Moreover, the rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more the average particle diameter of the prescribed filler, and a width of 0.2 mm or greater is 90% or greater. Such a rectangular area has a long-side direction that is substantially parallel to the long-side direction of the filler disposition film, and a widthwise direction that is substantially parallel to a short-side direction of the filler disposition film. The average particle diameter of the regularly disposed filler is from 0.4 μm to 100 μm.
