The resonance D*sJ (2317) which is considered to be the 13P0 state composed of charm and strange quarks has been discovered recently. The measured mass, which is about 160 MeV lower than the mass of the 13P0 state obtained from the potential model calculation by Godfrey and Isgur, was considered surprisingly low and attracted a lot of theoretical investigations. We calculate the mass shift of the 13P0 state by using the coupled channel e#ect. Our result shows that the coupled channel e#ect naturally explains the low mass of D*sJ (2317).
