Abstract
A fluorescence detecting device is configured so that a semiconductor integrated circuit substrate includes a photodiode and a signal detecting circuit for detecting charges obtained as a result of photoelectric conversion by the photodiode, and a fluorescence reaction vessel where a fluorescence reaction occurs is arranged above the foregoing photodiode. Furthermore, in the device, an excitation-light-entry preventing layer is provided at one or more of a surface portion of the photodiode and a position between the photodiode and the fluorescence reaction vessel.
