Abstract
This photodiode arrayincludes quenching resistorswhich are connected in series to respective avalanche photodiodes APDs, a peripheral wiring WL which surrounds a region in which the plurality of avalanche photodiodes APDs are formed, and a plurality of relay wiringswhich are electrically connected to the peripheral wiring WL, so as to respectively connect at least two places of the peripheral wiring WL. One of an anode and a cathode of each avalanche photodiode APD is electrically connected to any one of the relay wiringsvia the quenching resistor, and the other of the anode and the cathode of each avalanche photodiode APD is electrically connected to another electrodeprovided on a semiconductor substrate.
