PROBLEM TO BE SOLVED: To provide a polyester ultrafine yarn also retaining, inherent in a conventional ultrafine textured polyester yarn, a performance such as soft touch, moisturizability, water-absorbability, or hygroscopicity, and capable of obtaining a polyester fabric having ultraviolet-blocking effects and antistatic performance of excellent laundering durability as well, and to provide a method for stably producing the ultrafine polyester yarn. SOLUTION: The ultrafine false-twist textured polyester yarn consisting of sheath/core conjugate fibers is such that, the core is formed of an ultraviolet-absorbing polyester containing 0.1-5.0 wt.% each specific antistatic agent and organic ultraviolet light absorber, with respect to the polyester, and has each a specific single filament fineness, conjugate ratio, single filament tenacity, and yarn friction breakdown voltage.
