  We have carried out a deep X-ray observation on a typical Galactic plane
region with the Chandra ACIS-I instrument with unprecedented sensitivity and
spatial resolution, and detected 274 unidentified X-ray point sources in the
\~500 arcmin2 region. In order to identify these new X-ray sources, we have
carried out a near infrared follow-up observation using ESO/NTT infrared camera
on 2002/7/28 and 2002/7/29. Initial results are briefly reported.
