   We propose a 40ks ASCA observation for the flat-spectrum narrow-line
   Seyfert (NLS1) galaxy Mrk507. ROSAT observations shows that this
   object shares the soft X-ray properties; fast variability, the lack
   of X-ray absorption, and large X-ray luminosity (Lx=1E43 erg/s), with
   NLS1 class objects. However, the spectral slope (photon-index 1.6) is
   exceptionally flat among the NLS1s (mean photon-index 3.4). The flat
   spectrum is good for the hard X-ray observation, and a spectroscopy
   with ASCA provides a new insight to the peculiar nature of NLS1
   objects. We also intend to observe the bright Seyfert 1 galaxy Kaz163
   10.7 arcmin away from Mrk507 at the same time.
