PROBLEM TO BE SOLVED: To obtain a cut pile fabric having a core-sheath conjugate fiber kneaded with a matting agent as a pile fiber, which solves a whitish appearance without impairing coloring quality of pile surface by changing the cross sectional structure of the core-sheath conjugate fiber and an application method of the matting agent to be kneaded. SOLUTION: A core-sheath polyester conjugate fiber comprising a polyester having a matting agent content of <0.1 wt.% as a core component and a polyester having a matting agent content of≥0.8 wt.% as a sheath component, in which the core component constitutes a fiber core 11 and the sheath component constitutes a sheath layer 12 covering the fiber core is used as a cut pile. The core-sheath polyester conjugate fiber has a single fiber fineness of 1.0-5.5 dtex. Its cross section is formed into a flat cross-sectional shape having recessed parts 14 depressed inside and projecting parts 15 projecting outside. The area occupation ratio of the sheath layer in the cross-section is 10-50%. The amount k of the matting agent coated, which is expressed as the product of the thickness t of the sheath layer and the content w of the matting agent is preferably 2.5-5.5.
