To enhance not only heat resistance and chemical resistance but also dynamic properties and dimensional stability of a long fiber nonwoven fabric made of a core/sheath fiber using a polyarylene sulfide as a sheath component.
The long fiber nonwoven fabric uses a composite long fiber consisting of a sheath component containing not less than 95 pts.mass polyarylene sulfide and a core component containing a thermoplastic resin satisfying the relationship of TmcTmsTmc+30C between a melting point Tmc (C) of the core component and a melting point Tms (C) of the sheath component and the relationship of TgcTgsTgc+30C between a glass transition point Tgs (C) of the sheath component and a glass transition point Tgc (C) of the core component in a weight ratio of the core component to the sheath component of 40-60 to 60-40 and is formed by integrating the composite long fibers by bonding, wherein the strength of a single fiber in the composite long fiber is not less than 3.0 cN/dtex and the dry heat shrinkage percentage at 180C (SHD180) of the single fiber is not more than 10%.
