<p>Provided is a fluorescent endoscope which can easily decide whether a body cavity tissue in an observation region is a benign tissue or a malignant tissue upon observing a fluorescent light generated from the entire internal wall surface of a body cavity as an examinee. The fluorescent endoscope includes: an insert portion (5) which is inserted into a body cavity (3); a balloon (15) which is brought into contact of the internal wall of the body cavity (3) positioned in the radial direction of the insert portion (5) so as to position the insert portion (5) with respect to the body cavity (3) in the radial direction of the insert portion (5); light emission introduction portions (17, 19) which emit excited light to be applied to the internal wall outside of the radial direction and introduces the fluorescent light generated from the internal wall to inside the insert portion (5) from a plurality of different radial directions; an imaging unit (21) which images the fluorescent light introduced from the light emission introduction portions (17, 19); a correction signal calculation unit (57) which calculates a correction signal used for correcting the imaging signal outputted from the imaging unit (21) according to the distance between the contact surface of the balloon (15) with the internal wall and the insert portion (5); and a signal processing unit (57) which corrects intensity of the imaging signal according to the correction signal and generates an image signal from the corrected imaging signal.</p>
