Suzaku observed the Galactic center region near the Radio Arc at 20' southeast of Sagittarius A*. In the 18'*18' field of view, we found four distinct X-ray sources: a bright star and a diffuse source associated with the star clusters in the soft band (0.5-2.0 keV), a small clump in a higher energy band (4-6 keV), and a peculiar clump in the 6.4 keV line band. The latter two clumps are located at the south end of the Radio Arc. This paper reports on the results, and discusses the origin of these X-ray sources, with a particular emphasis on small clumps.
