摘要：

A light-receiving sensor (1) 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 (T1) and a terminal (T2). The first current source (CS) is also driven by the voltage between the terminals which voltage is obtained when no light is inputted.
