Abstract
Each light detecting unit includes a semiconductor region that outputs a carrier, and a surface electrode. In a photodiode array, a read wire is positioned between neighboring avalanche photodiodes. When a plane including a surface of the semiconductor region is set as a reference plane, a distance tb from the reference plane to the read wire is larger than a distance to from the reference plane to the surface electrode.
