We study the bound of the noncommutativity parameter in the noncommutative Schwarzschild black hole which is a solution of the noncommutative ISO(3,1) Poincare gauge group. The statistical entropy satisfying the area law in the brick wall method yields a cutoff relation which depends on the noncommutativity parameter. Requiring both the cut off parameter and the noncommutativity parameter to be real, the noncommutativity parameter can be shown to be bounded as Theta > 8.4 x 10(-2) lp.
