Abstract

An elastic multilayer body is provided with excellent elastic characteristics, film durability, and productivity. The elastic multilayer body includes a nonwoven material and a layer that includes an elastomer composition. The elastomer composition includes (a) polyurethane elastomer, (b) styrene-isoprene-styrene copolymer, and (c) 0 mass% or more and less than 4 mass% of a tackifier based on the amount of the elastomer composition. The amount of the component (a) is between 90 and 99.9 mass% based on the total amount of components (a) and (b). The amount of the component (b) is between 0.1 and 10 mass% based on the total amount of components (a) and (b).
