   Lupus3 is the nearby(140pc) star forming region with a high star
   forming effciency of >6%. Half of the whole emission-line objects (T
   Tauri) in the lupus region(1-4) extending to 10deg are concentrated
   within this reion (1 square degree). Any of the IRAS point sources do
   not coincides with the soft X-ray sources observed by ROSAT PSPC, on
   the other hand, many emission-line objects coincide with the soft
   X-ray sources. This indicate that there exist many deeply embedded
   sources such as youngest protostars which are visible in the hard
   X-ray (>5keV) observation same as the case of the ASCA observation of
   Rho Ophiuchi dark cloud.
