PROBLEM TO BE SOLVED: To obtain a polyester-based filament nonwoven fabric that has a low shrinkage percentage, improved dimensional stability and adhesion properties. SOLUTION: The filament nonwoven fabric comprises a conjugate filament having a fiber cross section of a multifoliate complex cross section. In the multifoliate complex cross section, a polyalkylene terephthalate-based polymer is arranged in the core part and a copolyester that comprises a terephthalic acid component, an ethylene glycol component and a 1,4-butanediol component and has a melting point lower than that of the polyalkylene terephthalate of the core part is placed in the leaf parts. Both the core part and the leaf parts are exposed to the fiber surface. COPYRIGHT: (C)2005,JPO&NCIPI
