Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyester-based conjugate fiber excellent in stretching property. SOLUTION: This polyester conjugate fiber is provided by joining a block copolymer A consisting mainly of 50-95 mass% of polytetramethylene terephthalate component and 5-50 mass% of polyoxytetramethylene glycol component and satisfying the following (a), with a polymer B containing ≥95 mol% of polyethylene terephthalate component. (a) 2.4≤Mw/Mn [wherein, Mn is a number-average molecular weight; Mw is a weight-average molecular weight; and (Mw/Mn) is the degree of distribution of the molecular weight].
