PROBLEM TO BE SOLVED: To provide aliphatic polyester-based conjugate fibers having excellent mechanical properties, heat resistance and wear resistance, therefore excellent in the process passableness in its yarn manufacturing and fabric manufacturing including yarn processing, warping and weaving, and also affording high wear resistance as a product. SOLUTION: The sheath-core conjugate fiber is such one that the thermoplastic resin constituting the core is an aliphatic polyester and the thermoplastic resin constituting the sheath is a fiber-forming polyamide, wherein the film thickness of the polyamide constituting the sheath is≥0.4μm.
