A transmission power control target value calculating apparatus that calculates target values, which are used for transmission power control of radio waves sent through radio transmission paths, comprises: a first target value calculating section that calculates a first transmission power control target value based on quality of combined data which is obtained by combining data obtained through the radio transmission paths; and a second target value calculating section that determines a second transmission power control target value to be applied to at least one of the radio transmission paths, based on the first transmission power control target value and quality information of each of the radio transmission paths.
