To provide a current control circuit which outputs a current following the variance of a low frequency and can suppress the output of the current following the variance of a high frequency by controlling a collector current and outputting a current in accordance with the collector current.

A current control circuit 51 constitutes a low band pass filter, LPF and a minute current ΔI corresponding to only the variance of a low frequency is obtained among the variances of a power supply voltage Vcc according to the set value of cut-off frequency of the LPF. The circuit 51 outputs a current following the variance of a low frequency if the voltage Vcc varies at a low frequency level and can suppress the output of a current following the variance of a high frequency if the high frequency noises are mixed into the voltage Vcc to vary at the high frequency. Therefore, if the noises are mixed into the voltage Vcc at a specific frequency level, the cut-off frequency is set to attenuate the noises and the constants can be set for resistance elements R1 and R2 and a capacitor C, respectively.
