PROBLEM TO BE SOLVED: To provide a filament nonwoven fabric for three-dimensional molding and for obtaining the molded product having good shape-keeping properties even at a high temperature. SOLUTION: The filament nonwoven fabric for the three-dimensional molding comprises thermoplastic filaments as constituent filaments. The constituent filaments are bonded with a thermally crosslinking type adhesive to each other. The thermally crosslinking type adhesive is substantially in an uncrosslinked state before the molding, and is crosslinked at the molding. The filament nonwoven fabric contains the thermally crosslinking type adhesive in a proportion of 10-30 wt.%. The filament nonwoven fabric for the three-dimensional molding is deformed to a prescribed three-dimensional shape, and thereafter heated to crosslink the thermally crosslinking type adhesive substantially in the uncrosslinked state. At the time, the nonwoven fabric is molded to the prescribed three-dimensional shape to provide the molded product. COPYRIGHT: (C)2007,JPO&INPIT
