Abstract

An optical receiving circuit which suppresses a characteristic deterioration due to a wiring between a PD and a TIA and a method for manufacturing the optical receiving circuit are provided. A optical receiving circuit () comprises a photodiode (), and a transimpedance amplifier () that supplies an electrical power source to the photodiode (). The characteristic impedance of a wiring between the anode of the photodiode () and the transimpedance amplifier () is higher than the characteristic impedance of a wiring between the cathode of the photodiode () and the transimpedance amplifier ().
