We examined effects of deposition temperatures and collector radii on the yields of fullerenes by arc discharge. Yields of fullerenes were 7-10%, 4 -6% and 0.5-1% in the liquid nitrogen-cooling, water-cooling, non-cooling, respectively, and were better with a collector radius of 50 mm than with that of 30 mm. The weight ratios of C60/C70 are about one for all runs of experiments.
