Abstract

According to one embodiment, a sensor includes a first avalanche photodiode, a first quenching element, a second avalanche photodiode, and a second quenching element. The first quenching element is connected to a current output terminal of the first avalanche photodiode at one end and is connected to an output terminal at another end. The second avalanche photodiode is arranged adjacent to the first avalanche photodiode. The second quenching element is connected to a current output terminal of the second avalanche photodiode at one end and is connected to a specific electric potential at another end.
