A current control circuit comprises a first NMOS for controlling a current supplied to a load connected to a drain; a second NMOS, the gate of which is connected to a gate of the fist NMOS; a resistor connected between the drain of the second NMOS and the power source; and an operational amplifier, the first input terminal of which is connected between the drain of the second NMOS and the resistor, to the second input terminal of which a control signal for adjusting an intensity of the current supplied to the load is inputted, the output of which is connected to a common connection point between the gates of the first NMOS and the second NMOS.
