Provided is a light receiving circuit including: a photodiode; a first amplifier including a feedback resistor connected between an input and an output of an inverting amplifier and having an input connected to a cathode of the photodiode; a second amplifier having a configuration similar to that of the first amplifier and having an input connected to an anode of the photodiode; a capacitor element connected between an output of the first amplifier and the input of the second amplifier; and a bias current control circuit that outputs a bias current to the input of the second amplifier according to a current value of the photocurrent, and controls an output voltage signal of the light receiving circuit according to an output of the second amplifier by using the bias current to adjust the sensitivity. The bias current control circuit changes the sensitivity according to the output of the second amplifier.
