PROBLEM TO BE SOLVED: To obtain a polyester-based core-sheath conjugate false twist yarn which is a multifilament composed of a polyester-based core-sheath conjugated fiber containing a titanium oxide fine particle in the core part, has uniform fineness of the multifilament in the length direction and each different crosssectional shape of single filaments of the multifilament cross section so as to provide a woven fabric and knitted fabric with see-through preventing properties and a dry feeling. SOLUTION: In the false twist yarn being the multifilament composed of the polyester-based core-sheath conjugate fiber containing the titanium oxide fine particle in the core part, the fineness of the multifilament is uniform in the length direction and the crosssectional shapes of the single filaments of the multifilament cross section are different, respectively.
