PROBLEM TO BE SOLVED: To obtain an antistatic polyester fiber having a good antistatic property and capable of being dyed into various kinds of colors by forming a sheath component having a specific thickness and containing a matting agent on the periphery of a core component containing an antistatic agent and a matting agent. SOLUTION: This antistatic polyester fiber is a sheath-core type conjugate antistatic polyester fiber. Therein, the core component contains a matting agent such as titanium dioxide in an amount of 0.6-10 wt.% and an antistatic agent such as a blocked polyetheramide containing 1-10 wt.% of R-SO3M groups [R is an 8-15C alkyl; M is an alkali (earth) metal] in an amount of 0.2-3 wt.% based on the total weight of the fiber. The antistatic agent and the matting agent are preferably adjusted in a weight ratio of 0.3-2.0. The sheath component contains a matting agent in an amount of <0.8 wt.%, and has a thickness of >=1.5μm in the diameter direction of the fiber. The antistatic polyester is preferably cut in a length of <=150 mm to prepare staple antistatic polyester fibers.
