We present results of phase shift for I=2 $S$-wave $pipi$ system with the Wilson fermions in the quenched approximation. The finite size method proposed by Luscher is employed, and calculations are carried out at $beta=5.9$ ($a^{-1}=1.934(16)$ GeV from $m_rho$) on $24^3 times 60$, $32^3 times 60$, and $48^3 times 60$ lattices.
