Recent results of exotic states with heavy quarks, denoted as XYZ states, are presented. The results include searches for the Y(4260) in B meson decays, a spin partner of Y(4630), and the strange Pentaquark . An addition, the measurements of the absolute branching fraction of X(3872) and search for double Zc production is dicussed.
