Abstract
A laminated glass includes first and second glass plates. First and second interlayers are arranged on the first and second glass plates, respectively. The first and second glass plates are arranged so as to have the first and second interlayers face each other. An enclosing layer is arranged between the first and second interlayers. The enclosing layer includes a functional member having a sidewall, and a dummy layer arranged on the sidewall, the functional member including one or more transparent layers. The functional member has a thickness of 200 μm at a maximum. The dummy layer is made of a thermoplastic resin. When denoting an average refractive index of the transparent layers included in the functional member as nA, and denoting a refractive index of the dummy layer as nB, a difference Δn of the refractive indices expressed by an absolute value |nA−nB| is 0.05 or less.
