PROBLEM TO BE SOLVED: To provide a mobile communication device capable of precisely controlling electric power with a simple circuit configuration while reducing converging time. SOLUTION: There are provided a power amplifier 103 for amplifying transmission signals, error detecting means (106, 107, and 108) for detecting an error between the electric power value acquired by detecting a part of the power of transmission signals amplified by the power amplifier 103 and the transmission power set value designated by a transmission power designator 113, a loop gain generator 110 which periodically switches two loop gain values of different magnitude at a prescribed time ratio for outputting, a loop gain multiplier 109 which multiplies the error detected by the error detecting means with the loop gain value outputted from the loop gain generating part 110 for outputting an error value, and an feedback amount generator 111 which generates feedback amount by integrating the error value outputted from the loop gain multiplier 109.
