To provide a napped artificial leather having a deep color and excellent in color migration resistance while maintaining a high-class feeling of a surface appearance and a soft feeling in a napped artificial leather comprising a fiber entangled body obtained by entangling colored ultra fine fibers.SOLUTION: A napped artificial leather comprises a fiber entangled body obtained by entangling colored fibers having an average diameter of 0.7 to 7 μm and (meth) acrylic polymer particles attached to a surface of the fibers and having an average particle diameter of 0.1 to 0.9 μm, and has a napped surface on which a fiber is napped. The fibers include a color pigment in an amount of 1 to 8 mass%. The napped surface has a lightness L*value of 20 or less.SELECTED DRAWING: Figure 1 【課題】着色された極細繊維を絡合させた繊維絡合体を含む立毛人工皮革において、表面外観の高級感とソフトな風合いを維持させながら、濃色で耐色移行性に優れた立毛人工皮革を提供する。【解決手段】着色された平均直径０．７〜７μｍの繊維を絡合させた繊維絡合体と、繊維の表面に付着した平均粒径０．１〜０．９μｍの（メタ）アクリル系ポリマー粒子とを含み、繊維を立毛させた立毛面を有し、繊維は着色顔料を１〜８質量％含み、立毛面は、明度Ｌ*値が２０以下である立毛人工皮革。【選択図】 図１
