Exotic hadrons reported in the heavy flavor sector have attracted much interest in hadron and nuclear physics. Especially near the thresholds, the hadron-hadron interaction is important to understand these exotic structures. In this talk, the short range πJ/ψ − DD̅* potential whose importance is indicated by the Lattice QCD is studied by the D(*) meson exchange model, and the Born-order quark exchange model. We find the large difference between the results of the D(*) meson exchange and the quark exchange calculations.
