PROBLEM TO BE SOLVED: To maintain a small diameter of an endoscope, and to perform both of normal imaging with a visible light and fluorescence imaging. SOLUTION: In the endoscope system, a plurality of imaging devices that detect a reflected light of an illumination light reflected by a somatoscopy part or an emitted light emitted by the somatoscopy part are arranged in series in the distal end portion of an endoscope, each of the plurality of imaging devices includes a light splitting means that deflects a part of the reflected light or the emitted light by 90°and transmits a part of the reflected light or the emitted light and an image pickup device that detects the reflected light or the emitted light deflected by 90°, the rearmost imaging device includes an optical path changing means that deflects the reflected light or the emitted light by 90°and an image pickup device that detects the reflected light or the emitted light deflected by 90°, and an observation optical member in which the light splitting means and the optical path changing device are arranged in series is provided.
