Abstract: PROBLEM TO BE SOLVED: To provide a bulky three-dimensional sheet material which has a good feeling, a good appearance and a high projected portion shape-retaining property. SOLUTION: This three-dimensional sheet material 10 is obtained by laminating the second fiber layer 1 comprising thermally non-shrinkable fibers to one side of the first fiber layer 2 containing thermally shrunk thermally shrinkable fibers. Both the fiber layers are integrated with many thermally fused portions 3 partially formed in the thickness direction by a thermally fusing method. Between the thermally fused portions 3, the fiber layer 2 is thermally shrunk to project the second fiber layer 1, thus forming many projections 4 and simultaneously forming dent portions at the thermally fused portions 3. The thermally fused portions 3 are formed by the melting and solidifying of a thermally fusing resin having a higher melting point TM than the thermally shrinkage-starting temperature TS of the thermally shrinkable fibers.
