ASCA Deep Sky Survey (DSS) is aimed to investigate the constituents of the CXB in 2–10 keV band, by faint source survey observations reaching to the source confusion limit of ASCA X‐Ray Telescopes. So far, 0.29 deg 2 sky regions were systematically studied and about 40% of the CXB intensity was resolved into discrete sources. In this paper, we present the latest results on the number‐flux relation (Long N ‐Log S ) and spectrum properties of faint X‐ray sources.
