Simulations are made with a renormalization group improved gauge action at $\\beta=2.6$ and 2.9 corresponding to $a^{-1}\\approx 2$GeV and 3GeV. Effects due to finite fifth dimensional size $N_5$ and finite spatial size $N_\\sigma$ are examined in detail. Matching to the continuum operator is made perturbatively at one loop order. We obtain $B_K(\\mu = 2 {GeV})= 0.5746(61)$, where the error is statistical only, as an estimate of the continuum value in the $\\msbar$ scheme with naive dimensional regularization.
