Anti-decuplet penta-quark baryon is studied with the quenched anisotropiclattice QCD for accurate measurement of the correlator. Both the positive andnegative parity states are studied using a non-NK type interpolating field withI=0 and J=1/2. After the chiral extrapolation, the lowest positive parity stateis found at m_{Theta} \simeq 2.25 GeV, which is too massive to be identifiedwith the experimentally observed Theta^+(1540). The lowest negative paritystate is found at m_{Theta}\simeq 1.75 GeV, which is rather close to theempirical value. To confirm that this state is a compact 5Q resonance, a newmethod with ``hybrid boundary condition (HBC)'' is proposed. The HBC analysisshows that the observed state in the negative parity channel is an NKscattering state.Comment: A talk given at International Workshop PENTAQUARK04, July 20-23, 2004  at SPring-8, Japan, 8 pages, 7 figures, 2 table
