We report the competition and coexistence between the Kondo effect and anisotropic gap induced by the antiferromagnetic ordering in CexNd1-xB6. Although the competition between the Kondo effect and superconducting gap have been reported extensively, such a competition in the antiferromagnetic Kondo compounds has been scarcely reported. The gap (Delta) effect is observed in a x region around x0.4 in the present system, which may be because TK is close to TN which corresponds to Delta.
