摘要：

Self-consistent APW band calculations are carried out for non-magnetic states of transition-metal intermetallic compounds having Cu2Sb-type crystal structure. The energy dispersions, densities of states and Fermi surfaces are shown. Differences and similarities of the electronic band structures of Cr, Mn, Fe-arsenides are clarified. To discuss the bonding nature, calculations of the bond order are also carried out.
