A wireless base station (100) calculates a first transmission rate when performing transmission to a wireless terminal with communication path quality by a first transmission power in a first candidate band selected as a candidate from first wireless bands including a neighboring priority band, calculates a second transmission rate when performing transmission to the wireless terminal (200) with the communication path quality by a second transmission power in a second candidate band selected as a candidate from second wireless bands that do not include the neighboring priority band, and sets, out of a first wireless resource including the first transmission power and the first candidate band and a second wireless resource including the second transmission power and the second candidate band, a wireless resource for a higher transmission rate obtained by the calculation as a wireless resource allocatable to the wireless terminal (200). It is therefore possible to maximize the throughput of the wireless terminal existing in the local station communication area while implementing suppression of interference to the neighboring cell.
