PROBLEM TO BE SOLVED: To prevent deterioration of photocurrent and optical response from occurring. SOLUTION: A semiconductor photodetector is provided with a substrate and a photodetecting element. The substrate is provided with an electric circuit. At least a first metal layer and a second metal layer are formed on the surface. The first metal layer and the second metal layer are electrically connected to a corresponding electrical signal input/output node of the electric circuit of the substrate. The photodetection element is a semiconductor photodetecting element, and the bottom end is connected to the substrate. The photodetecting element receives an incident light by transmitting an upper end. COPYRIGHT: (C)2006,JPO&NCIPI
