PROBLEM TO BE SOLVED: To provide a means for eliminating a moire in a fluorescent endoscopic device that occurs in an image to be obtained when a fluorescent image propagated by an image guide is photographed. SOLUTION: A fluorescent endoscopic device in which a fluorescent image Zk generated from a biological tissue 1 and received an irradiation of an excitation light Le is allowed to be propagated to its edge 21B, and the fluorescent image Zk thus propagated to the edge 21B is formed into an image by a means to produce fluorescent images 30 through spectral distribution over mutually different three wavelength areas and photographed by highly sensitive photographing elements 41, 42 and 43 where a phase plate 81 such as a quartz crystal birefringent plate, or the like, is placed between a switching mirror 39 and a dichroic mirror 35.
