Abstract
【解決手段】内視鏡の挿入部先端に連設された先端部16aには、送気・送水ノズル22、観察窓28、照明窓29a,29bが設けられ、互いに平行な第1及び第2の平坦面33a,33bが形成されている。観察窓28の表面は、第1の平坦面33aよりも先端側に位置する第2の平坦面33bと同じ位置に配されている。送気・送水ノズル22に対向する位置には、第1の平坦面33aと第2の平坦面33bとの間を繋ぐ傾斜面38が形成されている。傾斜面38の両側には流体ガイド面39a,39bが形成されている。流体ガイド面39a,39bは、照明窓29a,29bに向かって傾斜する。送気・送水ノズル22から噴射された流体は傾斜面38に当たって観察窓28に拡がるとともに、流体ガイド面39a,39bに導かれて照明窓29a,29bへ流れる。
