Although they have been studied extensively,there still remain a few fundamental problems. In the present paper,we report the results of our recent Monte Carlo simulation of the three-dimensional ±J Ising spin glass,focusing on a theoretical issue concerning the nature of the low-temperature phase. 3) We present our Monte Carlo results in the next section. The order-parameter distribution function P (q) exhibits a feature of the droplet picture of the lowtemperature phase: P (0) decreases at T =0 .3 as the system size is increased. This conclusion is not completely consistent with many of previous Monte Carlo results at higher temperatures. 4) - 6)
