Abstract

A three-dimensional sheet (10) which comprises a first fibrous layer (1) comprising heat-shrinkable fibers which have undergone heat shrinkage, a second fibrous layer (2) which has been superposed on one side of the layer (1) and which comprises non-heat-shrinkable fibers as the main component and contains fusion-bondable fibers, and a third fibrous layer (3) superposed on the other side of the first fibrous layer (1) and comprising fusion-bondable fibers, wherein the first to third fibrous layers have fusion-bonded parts (4) arranged so as to form a given pattern in the three-dimensional sheet, the fusion-bonded parts (4) extend from the second fibrous layer (2) to the third fibrous layer (3), and the second fibrous layer (2) is convex in their parts other than the fusion-bonded parts (4).
