PROBLEM TO BE SOLVED: To provide an endoscope capable of always capturing a clear image by reliably removing a cleaning fluid remaining at the small-diameter tip of the endoscope when washing the tip, with an extremely simple constitution.SOLUTION: The endoscope comprising an insertion part to be inserted to the inside of an observation target comprises: a tip face 40 which is configured at the tip of the insertion part and includes a transparent optical area for guiding light to an image sensor 17 and a water pouring part 38 which discharges the cleaning fluid for washing a range equivalent to at least the optical area of the tip face 40. A water repellent coat is applied to the range of the optical area, and a hydrophilic coat area 52 is provided at a part facing the water pouring part 38 across the optical area, on the tip face 40.COPYRIGHT: (C)2015,JPO&INPIT【課題】極めて簡易な構成で、細径化された内視鏡の先端部を洗浄する際に、先端部に残留する洗浄液を確実に除去し、常に鮮明な画像を撮像することが可能な内視鏡を提供する。【解決手段】観察対象の内部に挿入される挿入部が設けられた内視鏡であって、挿入部の先端に構成されてイメージセンサ17に光を導く透明な光学領域を含む先端面40と、先端面40の少なくとも光学領域に相当する範囲を洗浄する洗浄液を吐出する注水部38と、を備え、光学領域の範囲に撥水コートを施し、先端面40において、光学領域を挟んで注水部38と対向する部位に、親水コート領域52を備える。【選択図】図4
