Abstract
A semiconductor element including an array in which a plurality of avalanche photodiodes is arranged includes a plurality of first electrodes configured to receive supply of a first voltage to be used by the plurality of avalanche photodiodes from outside, and at least one second electrode configured to receive supply of a second voltage from outside different from the first voltage. The plurality of first electrodes and the at least one second electrode are disposed outside the array. The at least one second electrode is disposed between one and another one of the plurality of first electrodes.
