We observed sub-km MBAs by Subaru telescope + Suprime-Cam with the B-, v-, R-, I-filters for investigating their colors. We surveyed 6 fields of Suprime-Cam's FOV (in total 1.5 deg^2) near ecliptic plane and near opposition. We detected 163 MBAs with the 4 bands. We will report their color distribution and also a correlation between color and orbital distributions.
