PROBLEM TO BE SOLVED: To provide a polyester-based conjugated fiber which has excellent stretchability and excellent textile, little has fuzzes, and has a high quality. SOLUTION: This polyester-based conjugated fiber produced by adhering a polyester component A containing trimethylene terephthalate as main repeating units and having an intrinsic viscosity of 0.8 to 1.5 to a polyester component B containing ethylene terephthalate as main repeating units and having an intrinsic viscosity of 0.3 to 0.7 in an A:B weight ratio of 30:70 to 70:30 in a side-by-side type or an eccentric sheath-core type is characterized in that the total content of antimony and germanium metal elements in the conjugated fiber is≤20 ppm.
