  To understand luminous AGNs in the z<1 universe, the ASCA AGN samples are the
best at present. Combining the identified sample of AGNs from ASCA Large Sky
Survey and Medium Sensitivity Survey, the sample of hard X-ray selected AGNs
have been expanded up to 108 AGNs above the flux limit of 10^{-13} erg s^{-1}
cm^{-2} in the 2-10 keV hard X-ray band. We discuss the fraction of absorbed
AGNs in the hard X-ray selected AGN sample, and nature of absorbed luminous
AGNs.
