PROBLEM TO BE SOLVED: To provide a conjugated hollow polyester fiber excellent in high bulkiness and bulkiness-recovering. SOLUTION: This conjugated hollow polyester fiber comprises 2 kinds of polyesters having different intrinsic viscosities side by side, and having 10-50% hollow rate, three dimensional crimps of 5-20 crimps/25 mm number of crimps and≤5% dry heat shrinkage.
