<p>PROBLEM TO BE SOLVED: To provide a laminate having a structure that is less susceptible to denting of apex portions even when screens having concavo-convex surfaces are stacked.SOLUTION: A laminate comprises a plurality of screens (10), each having a concavo-convex surface with apexes (13c) formed thereon, and foam sheets (10), each placed between the screens. The foam sheet has an expansion ratio of 15 times or more, compressive hardness of 6 N/cmor less, and thickness variation of 10% or less.</p> |
