PROBLEM TO BE SOLVED: To provide an ultrafine polyester blended yarn having excellent antistaticity and suitable for a soft and high-repulsion worsted-like woven fabric having wool-like touch. SOLUTION: The antistatic ultrafine polyester blended yarn is constituted of a polyester multifilament yarn A of a core-sheath-type conjugate yarn in which the core part is formed of a polyester (a) containing a specific antistatic agent in a specified amount, and the sheath part is formed of a polyester (b) containing a matting agent of 0-10 wt.%, and which has a fineness of≤1.5 dtex, and a heat-shrinkable polyester multifilament yarn B. The polyester blended yarn is obtained by interlacing the multifilament yarns A and B by overfeeding them to an interlacing nozzle, subjecting the interlaced yarn to relax heat treatment to spontaneously elongate the polyester multifilament yarn, and further subjecting the obtained yarn to second relax heat treatment.
