The mass and decay constant of the ground state strange tensor meson K-2* (1430) with I(J(P)) = 1/2(2(+)) are calculated using the QCD sum rules method. The results are consistent with the experimental data. It is found that SU(3) symmetry breaking effect constitutes about 20% of the decay constant.
