At the tip of an insertion part of an endoscope, an object window for regular observation use is positioned at almost the center, directly connected to which, said object window for fluorescent observation use is provided, and at the both sides of the object window for regular observation use and the object window for fluorescent observation use, two illumination windows are provided. A forceps hole which is an opening part at the tip side of a forceps channel which is inserted into the insertion part is provided at the lower right of the object window for regular observation use, and a treatment tool which is inserted through a forceps insertion channel is to be extruded from this forceps hole. By this way, on monitor images at both of white light observation and fluorescent observation, the treatment tool such as a forceps or the like is designated at almost the same position to improve the manipulation capability.

Endoscopes and endoscope devices which image regular observation images and fluorescent images as well as which provide easier operation of treatment tools
