Abstract
A multilayer sheet includes a first resin layer, a second resin layer, a particle-containing layer disposed at least between the first and second resin layers and including plural particles and gaps formed between the particles, and an intermediate layer disposed at least one selected from between the first resin layer and the particle-containing layer or between the second resin layer and the particle-containing layer, including a copolymer having a weight average molecular weight (Mw) of 300,000 or more and a molecular weight distribution, expressed as a ratio of the weight average molecular weight (Mw) to a number average molecular weight (Mn), of 6.0 or less and a structural moiety derived from a crosslinking agent adapted to crosslink the copolymer, and having a crosslinking density of from more than 0 mol/m3 to 450 mol/m3.
