To provide a highly sensitive photodetector.SOLUTION: The photodetector includes: a plurality of photodetection elements 1; trenches 3 provided between the plurality of photodetection elements 1; and a wiring 4, provided between two photodetection elements 1 among the plurality of photodetection elements 1, electrically connected to the two photodetection elements 1. The trenches 3 surround 2m (m is a positive integer) photodetection elements 1 including two photodetection elements 1, in which the two photodetection elements 1 are arranged in a direction orthogonal to an extending direction of the wiring 4.SELECTED DRAWING: Figure 1 【課題】本発明が解決しようとする課題は、高感度な光検出器を提供する。【解決手段】上記の課題を達成するために、実施形態の光検出器は、複数の光検出素子１と、複数の光検出素子１の間に設けられるトレンチ３と、複数の光検出素子１の内、２つの光検出素子１の間に設けられ、２つの光検出素子１と電気的に接続する配線４と、を具備し、トレンチ３は、２つの光検出素子１を含む２ｍ（ｍは正の整数）個の光検出素子１を囲み、配線４の延伸方向と直交する方向に２つの光検出素子１が並ぶ。【選択図】 図１
