L'élément allongé comporte une section courbée côté extrémité distale de ce dernier. L'élément de nettoyage est configuré de telle sorte que, lorsque l'élément allongé est inséré à travers un canal d'insertion d'instrument de traitement dans l'endoscope et fait saillie depuis l'extrémité distale de l'endoscope, une ligne d'enveloppe de l'élément de nettoyage, la ligne d'enveloppe étant située côté surface de lentille de l'endoscope, comporte une partie qui n'est pas parallèle à un plan perpendiculaire à la direction axiale de l'endoscope. En outre, ce second dispositif de nettoyage de lentille pour un endoscope comprend : un élément allongé pouvant se déformer élastiquement ; un élément de nettoyage fixé à la surface périphérique externe de la section d'extrémité distale de l'élément allongé ; et un cylindre externe qui peut contenir l'élément allongé et l'élément de nettoyage. L'élément allongé comporte une section courbée située plus près du côté extrémité proximale que ne l'est l'élément de nettoyage, et l'élément de nettoyage fait face à la surface de la lentille de l'endoscope.
