To obtain the subject woven fabric suitable for textiles, composed of a polyester-based sea-island type conjugate filament fiber in which groove is formed in the longitudinal direction on the surface of filament without being divided.
In this woven fabric comprising a polyester-based sea-island type (it is preferred that a sea component 1 and an island component 2 have the difference of dissolving rates in an alkaline solution and the sea component 1 becomes a component which dissolves early than the island component 2) conjugate filament fiber, only the surface is dissolved without dividing the conjugate filament by alkaline treatment in the state of woven fabric. It is preferable that the island component 2 comprises a polyester polymer and the sea component 1 comprises a copolymer polyester polymer composed of a copolymer of terephthalic acid with 5-sodium sulfoisophthalic acid.
