Abstract
An endoscope includes an insertion part that includes a distal end and a proximal end, and a distal-end-portion body that is provided on a distal end side of the insertion part and formed with a treatment tool outlet from which a treatment tool is led out. The distal-end-portion body includes an observation window, a nozzle that ejects washing water to the observation window, a standing base that is disposed in a standing base-housing portion adjacent to the treatment tool outlet and is rotationally moved between a standing position and a falling position, and a guide wall that is disposed at a position facing the nozzle with the observation window interposed therebetween and guides the washing water to the standing base-housing portion. Washing water, which has been ejected from the nozzle and has passed the observation window, is guided to the standing base-housing portion by the guide wall.
