Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a core-sheath conjugated fiber without agglutination of yarns during heat treatment in the core-sheath conjugated fiber comprising a core component composed of a melt-anisotropic aromatic polyester and a sheath component having a sea-island structure. SOLUTION: The core-sheath conjugated fiber is obtained by applying 0.03-2.5 mass% of inorganic fine particles consisting essentially of a silicate compound to the fiber surface in the core-sheath conjugated fiber comprising the core component composed of the melt-anisotropic aromatic polyester (polymer A) and the sheath component having the sea-island structure and satisfying following (1) to (2). (1) the sheath component ratio is 0.2-0.7 and (2) the sea component composing the sheath component is composed of a flexible thermoplastic polymer (polymer B); the island component is composed of a melt-anisotropic aromatic polyester (polymer C) and the island component ratio in the sheath component is 0-0.25.
