A multilayer sheet (1) which is provided with: a first resin layer (10); a second resin layer (20); a particle-containing layer (30) which is arranged at least between the first resin layer (10) and the second resin layer (20) and contains a plurality of particles and voids (36) that are formed among the particles; and an intermediate layer (40) having a crosslinking density of more than 0 mol/m3 but 450 mol/m3 or less, which is arranged between the first resin layer (10) and the particle-containing layer (30) and/or between the second resin layer (20) and the particle-containing layer (30), and which contains a copolymer that has a weight average molecular weight (Mw) of 300,000 or more and a molecular weight distribution (Mw/Mn) expressed as the ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn) of 6.0 or less and a structural portion that is derived from a crosslinking agent capable of crosslinking the copolymer.
