PROBLEM TO BE SOLVED: To provide an air/water feeding device of an endoscope including a water supply bottle, capable of turning water to be blown to an observation window into an air-mixed atomization state, washing away even mucus or the like strongly stuck to the observation window, preventing water from being mixed in air to be fed when an air feeding operation is performed after an atomization operation, and preventing the rhythm of an endoscopic operation by an operator from being disturbed.SOLUTION: At a part positioned in the middle of a water feed pipe 22 in a space inside a water supply bottle 12, a vent hole 20 for atomization, for making pressurized air directly flow into the water feed pipe 22 and mixing it with water inside the water feed pipe 22 is formed, and the water to be blown to an observation window is turned to the air-mixed atomization state. |
