PROBLEM TO BE SOLVED: To provide a nonwoven fabric having not only excellent bulkiness and water absorption, but also high strength even in a wet state and also having soft feeling. SOLUTION: The water-absorbing nonwoven fabric structure is obtained by laminating each at least one layer of a nonwoven fabric A including≥70 wt% thermobonding core-sheath type conjugate staple fiber and free from a pulp fiber, and a nonwoven fabric B constituted of a thermobonding core-sheath type conjugate staple fiber and the pulp fiber, and thermobonding the thermobonding core-sheath type conjugate staple fiber to each other and/or the thermobonding core-sheath type conjugate staple fiber to the pulp fiber. A polytrimethylene terephthalate polymer is arranged in the core part in both of the thermobonding core-sheath type conjugate staple fiber included in the nonwoven fabric A and the thermobonding core-sheath type conjugate staple fiber included in the nonwoven fabric B, and the weight ratio of the pulp fiber to the whole of the nonwoven fabric structure is within the range of 20-80 wt%.
