Summary:PROBLEM TO BE SOLVED: To suppress deterioration of an S/N caused by the change over aging of an element temperature of due to the change of an external temperature in a simple configuration without enlarging the element area in a quantum well photo-detector. SOLUTION: A dummy quantum well element 3 equipped with a dummy quantum well layer 4 to be irradiated with high-directivity light 6 for operating transmission of light 5 to be detected is provided on the pre-stage of a quantum well element 1 for photo-detection.
