An optical receiver array includes a plurality of light-receiving elements, a plurality of amplifiers, and a plurality of low-pass filters. The light-receiving elements convert optical signals of a plurality of channels into electrical signals, respectively. The amplifiers amplify the electrical signals output from the light-receiving elements and output the electrical signals. Each amplifier has positive and negative power supply terminals to which power is supplied. Each low-pass filter is connected between the positive power supply terminal of a corresponding amplifier and a first external power supply terminal or between the negative power supply terminal of a corresponding amplifier and a second external power supply terminal. Each light-receiving element is connected between the positive power supply terminal and an input terminal of a corresponding amplifier or between the input terminal and the negative power supply terminal of a corresponding amplifier.
