PROBLEM TO BE SOLVED: To provide a multilayer structure which varies a three-dimensional structure by absorbing water made by bonding or sewing two or more sheet-like materials together and which can reduce a sticky feeling, a humid feeling and a cold feeling under the condition that concavities and convexities appear on the surface of the structure, a thickness increases or an air permeability enhances by absorbing water. SOLUTION: The multilayer structure is made by bonding or sewing two or more sheet-like materials together selected from the group consisting of a woven/knitted fabric and a nonwoven fabric wherein the multilayer structure contains a variable layer by absorbing water and a non-variable layer by absorbing water, and hence varies in three-dimensional structure by absorbing water. The area of the variable layer becomes larger in the water-absorbed state than in the dry state by 10% or more, or and/or only its thickness becomes larger by 10% or more. The non-variable layer by absorbing water has a percent change in the area and the thickness of 3% or less in the water-absorbed state than in the dry state. COPYRIGHT: (C)2007,JPO&INPIT
