We have performed local-density-functional band-structure calculations for a new high-To superconducting phase, YBa2Cu4Oa. General characteristics in the energy band are quite similar to those of YBa2CusOT. We have found a noticeable energy-level lowering of oxygen p-states at the chain and apex sit
