Abstract
A light-receiving sensor () includes: a photodiode (PD) for generating a photocurrent by use of a light input; and a first current source (CS), provided in parallel to the photodiode (PD), for generating a first auxiliary current by being driven by a voltage between terminals, which are a terminal (T) and a terminal (T). The first current source (CS) is also driven by the voltage between the terminals which voltage is obtained when no light is inputted.
