Abstract: Disclosed is an optical detector in which a boundary line BY defining an edge of a semiconductor region 14 is covered with signal read wiring E3 and a capacitor is configured between the semiconductor region 14 and the signal read wiring E3. High frequency components peak components of a carrier are quickly extracted to the outside via the capacitor, but the signal read wiring E3 covers the boundary line BY so that a semiconductor potential in the vicinity of the boundary line is stabilized and an output signal is stabilized.

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.
