X-ray detection below 10 keV has made great progress with a Charge Coupled Device (CCD). The greatest advantage to use CCD is that it has a good energy resolution as well as a high spatial resolution. Several efforts are done on the development of the X-ray CCD in Europe and in U. S. A. We present the results obtained with the CCD developed in MIT/Lincoln which is scheduled to be boarded on the next Japnese astronomy satellite Astro-D. Astro-D will be the first space observatory using the X-ray CCD. We also show the results obtained with CCD available in Japan. The requirements for the future X-ray CCD are discussed.
