    The broadband response of Asca XRT offers us the first chance to
    search for hard X radiation that may originate in the nuclear region
    of nearby spiral galaxies. If detected, such radiation could be the
    most secure basis for the presence of hidden AGN, especially in cases
    where evidence from other bands is ambiguous.Since low luminosity AGN
    are likely to have absorbed X ray spectra, existing surveys with
    Einstein and ROSAT are not suitable.The spatial and energy resolution
    of Asca are quite adequate for conducting a limited search using
    selected spiral at distances up to 30 Mpc. In obtaining candidate
    objects, we have made use of suggestive information,especially in the
    radio band.The goals of this project are better understandings of AGN
   and its contribution to CXB.
