We present the pre iminary results of the hard X‐ray global mapping of the Galactic Center region with ASCA . Many point sources and diffuse structures are resolved more clearly than before in the 2–10 keV band. Iron line emission is a so intensely distributed along the Galactic plane. It is interpreted that either high temperature plasma concentrates on the Plane, or the molecular clouds illuminated by externa strong X‐ray sources are densely distributed along the Plane, or possibly both mechanisms are important.
