PROBLEM TO BE SOLVED: To provide a filled polyester fiber not only having excellent abrasion resistance but also having dynamic fatigue resistance equal or superior to that of an unfilled polyester fiber. SOLUTION: The polyester fiber comprises an aliphatic-aromatic polyester and unlayered platelet-shaped particles. The unlayered platelet-shaped particles are selected from the group consisting of an inorganic oxide, a hydroxide, a carbonate, a bicarbonate, a nitride and a carbide, and have 20-100 nm thicknesses and≤20/1 aspect ratios.
