PROBLEM TO BE SOLVED: To provide a mobile communication device capable of highly accurately performing power control and shortening a convergence time in simple circuit configuration. SOLUTION: A mobile communication device includes: a power amplifier 103 for amplifying a transmission signal; error detection means (106, 107, 108) for detecting an error between a power value obtained by detecting a part of power of the transmission signal amplified by the power amplifier 103 and a transmission power setting value designated by a transmission power designating section 113; a loop gain generating section 110 which outputs a loop gain value while periodically switching two loop gain values of different magnitudes in a predetermined time ratio; a loop gain multiplying section 109 which multiplies the error detected by the error detection means by the loop gain value outputted from the loop gain generating section 110 and outputting an error value; and a feedback amount generating section 111 which generates a feedback amount by integrating the error value outputted from the loop gain multiplying section 109.
