<P>PROBLEM TO BE SOLVED: To provide a three-dimensional sheet excellent in liquid flow preventing properties, cushioning properties, the touch and the like, capable of obtaining sufficient joining strength in a heat fusion part and also excellent in liquid permeability. <P>SOLUTION: The three-dimensional sheet 10 is constituted so that a first sheet 1 and a second sheet 2, both of which are laminated mutually, are partially fused thermally to form the heat fusion part 4 and the first sheet 1 is protruded at a part other than the heat fusion part 4 to form a large number of protruded parts 5. The heat fusion part 4 has a shape long in one direction (Y-direction) of the plane direction of the three-dimensional sheet 10 and a large number of opening 41 are formed to the heat fusion part 4 so as to leave intervals in the longitudinal direction of the heat fusion part 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
