PROBLEM TO BE SOLVED: To provide a simple-structured and low-cost remote-controlled photodetector unit. SOLUTION: This detector unit comprises an integrated circuit 1 including amplifier circuits, etc., photodetector 2 mounted together with this integrated circuit 1 on a lead frame 3, and shield plate 4 facing the integrated circuit 1 and detector 2. The lead frame 3 and shield plate 4 are molded with a resin 5, including the integrated circuit 1 and photodetector 2. The photodetector 2 is mounted with its photodetecting face 2a fitted in a signal transmission opening 3a of the lead frame 3 and shield plate 4 is disposed at the back side 2b of the detector 2. |
