Abstract
We present the preliminary 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 emis sion is also intensely distributed along the Galactic plane. It is interpre ted that either high temperature plasma concentrates on the Plane, or the m olecular clouds illuminated by external strong X-ray sources are densely di stributed along the Plane, or possibly both mechanisms are important.
