摘要

A nonwoven fabric laminate which sequentially comprises a front surface layer, an intermediate layer and a back surface layer in this order, and which is configured such that: each of the front surface layer and the back surface layer is independently composed of a spun-bonded nonwoven fabric layer that contains filaments of a thermoplastic polyurethane elastomer (A) and filaments of a thermoplastic resin (B); the intermediate layer is composed of a spun-bonded nonwoven fabric layer that contains 50% by mass or more of filaments of a thermoplastic polyurethane elastomer (a); and the storage elastic modulus of the thermoplastic polyurethane elastomer (A) and the storage elastic modulus of the thermoplastic polyurethane elastomer (a) are 25.0 MPa or less, independently.
