 note = {We perform the first study of the static pentaquark (5Q) potential V5Q in SU(3) quenched lattice QCD with 163×32 and β=6.0. From the 5Q Wilson loop, V5Q is calculated in a gauge-invariant manner, with the smearing method to enhance the ground-state component. V5Q is well described by the OGE–plus–multi-Y ansatz: a sum of the one-gluon-exchange (OGE) Coulomb term and the multi-Y-type linear term proportional to the minimal total length of the flux tube linking the five quarks. Comparing with QQ¯¯¯ and 3Q potentials, we find a universality of the string tension, σQQ¯¯¯≃σ3Q≃σ5Q, and the OGE result for Coulomb coefficients.},
