In this article, we take the point of view that the charmed scalar meson D s0 (2317) be a tetraquark state and devote to calculate its mass within the framework of the QCD sum rules approach in the heavy quark limit. The numerical values for the mass of the D s0 (2317) are consistent with the experi
