PROBLEM TO BE SOLVED: To provide a conjugated fiber having both excellent moisture-absorbing or -releasing characteristic and excellent moisture-sensitive crimp characteristic. SOLUTION: A conjugated fiber in which a polyamide component is bound to a polyester component in a side-by-side type, is characterized by containing a polyether ester amide in the polyamide component in an amount of 0 to 15 wt.% based on the weight of the polyamide component and further containing the polyether ester amide in the polyester component in an amount of 15 to 55 wt.% based on the weight of the polyester component. The polyether ester amide is derived from a polyamide (a) having carboxyl groups at both the ends and having a number-average mol.wt. of 500 to 5,000 and a bisphenol compound-ethylene oxide adduct (b) having a number-average mol.wt. of 1,600 to 3,000, and has a relative viscosity of 1.5 to 3.0 (0.5 wt.% m-cresol solution, 25°C).
