In this paper, we study the first eigenvalue of Jacobi operator on ann-dimensional non-totally umbilical compact hypersurface with constant mean curvatureHin the unit sphere. We give an optimal upper bound for the first eigenvalue of Jacobi operator, which only depends on the mean curvatureHand the dimensionn. This bound is attained if and only if,is isometric towhenoris isometric to a Clifford torus, forwhen.
