The objective of the present invention is to provide a diversity receiver that detects differences in reception qualities for reception branches, and that controls the starting and halting of a diversity operation in accordance with the difference in the reception qualities, so that power saving is enabled and battery operating periods can be extended. A difference in reception levels (A, B) which are reception qualities for reception branches (13a, 13b), is employed to determine whether desired diversity effects are available or not. In a case wherein it is determined that desired diversity effects are not available, the diversity operation is halted and the supply of power to a reception branch that is not to be used is halted, and the combining operation is also halted.
