PROBLEM TO BE SOLVED: To provide a medical solution sprayer for an endoscope, capable of smoothly spraying an appropriate quantity of a medical solution into a living body without leaking the medical solution to soil hands of an operator or the periphery under the operator's hands. SOLUTION: The medical solution sprayer has a flexible tube 11, a solution filling bag 12 and a solution measuring bag 13, which are integrally formed. The flexible tube 11 can be inserted into/detached from an instrument insertion channel 3 of the endoscope. The solution filling bag 12 is filled with the medical solution to be fed into the flexible tube 11 and is made of an elastic material. The solution measuring bag 13 is connected/disposed between the rear end of the flexible tube 11 and the distal end of the solution filling bag 12, and is made of a transparent and elastic material. The medical solution sprayer also has a check valve 14 disposed between the solution filling bag 12 and the solution measuring bag 13. The check valve 14 lets the medical solution pass from inside the solution filling bag 12 to the inside of the solution measuring bag 13, while preventing the medical solution from passing from inside the solution measuring bag 13 into the solution filling bag 12.
