Abstract
In this article, we take the point of view that the be a tetraquark state, which consists of a scalar diquark and a vector antidiquark, and calculate its mass with the QCD sum rules. The numerical result indicates that the mass of the vector charmed tetraquark state is about or from different sum rules, which is about larger than the experimental data. Such tetraquark component should be very small in the .
