To provide a light detecting device that, with respect to a pixel that includes an inter-pixel separating portion of a conductive material, enables connection to ground without using special processing.SOLUTION: A light detecting device includes: a substrate portion that includes a pixel region in which a plurality of pixels capable of generating charge in accordance with externally entered light are arrayed in a matrix, and a peripheral region different from the pixel region. Each of the plurality of pixels is provided with a plurality of inter-pixel separating portions that define an outer edge of the pixel and are formed so as to extend from a light entry surface of the substrate portion to a surface thereof opposite the light entry surface, the inter-pixel separating portions insulating and blocking light between adjacent pixels. At least some of the plurality of inter-pixel separating portions are formed so as to extend to the peripheral region. The peripheral region is provided with a ground portion that is connectable to the inter-pixel separating portions and that are for applying a predetermined voltage to the pixels via the inter-pixel separating portions.SELECTED DRAWING: Figure 6 【課題】導電性材料の画素間分離部を含む画素に対し、特別なプロセスを使用することなく、グランドに接続できる光検出装置を提供する。【解決手段】光検出装置は、外部から入射した光に応じて電荷を生成可能な複数の画素が行列状に配置された画素領域と、画素領域とは異なる周辺領域とを有する基板部を備える。複数の画素のそれぞれは、画素の外縁を規定し、基板部の光入射面から光入射面とは反対側の面に至るように形成され、隣接する前記画素の間を絶縁して遮光する複数の画素間分離部を備える。複数の画素間分離部の少なくとも一部は、周辺領域まで延伸して形成される。周辺領域において、画素間分離部に接続可能で、画素間分離部を介して画素に所定の電圧を印加するための接地部を備える。【選択図】図６
