PROBLEM TO BE SOLVED: To provide a distal end part of an endoscope capable of blowing water jetted from a sub water sending port to the center position of an observation visual field regardless of a distance to an object. SOLUTION: By arranging a stream drawing member 7 acting to draw the water W jetted from the sub water sending port 4 to the side and bending the jetting direction so as to be freely moved forward and backward in the axial direction of an insertion part distal end 2 by remote control and moving the stream drawing member 7 forward and backward, the jetting angle of the water W jetted from the sub water sending port 4 is changed corresponding to the above movement.
