CONSTITUTION:A loop is formed by a filament consisting of a thermoplastic resin such as regenerated polyester resin to constitute a three-dimensional net- like structure. The outer circumferential length of the filament is selected within 0.3-15mm so that this loop has a sufficient compression strength, whereby the compression characteristics of the filament itself and the three-dimensional net-like structure are improved. A hollow part having a hollow ratio of 5-80% is provided so that the filaments are mutually adhered in the contact point. The thermoplastic resin is discharged from a plurality of orifices having the property of forming a plurality of hollow sections, the discharged filaments in the fused state are meandered to mutually make contact, and the contact parts are welded and adhered, and cooled while forming a three-dimensional structure, whereby the three-dimensional net-like structure is manufactured.
