Connect the air supply pipe that sends pressurized air to the tip of the insertion section and the liquid supply pipe that sends liquid, and also connect the air supply pipe connected to the air pressure source and the liquid supply pipe connected to the liquid supply tank, and connect the valve casing. A valve body is slidable for switching the air supply pipe between a state in which it communicates with the air supply pipe and a state in which it is opened to the atmosphere, and for bringing the liquid supply pipe into contact with and separating from the liquid supply pipe. In the liquid chamber, the liquid supply pipe is expanded by a certain volume after the liquid supply pipe is switched from a connected state to a disconnected state to the liquid supply pipe by movement of the valve body. A fluid supply valve for an endoscope, characterized in that the valve is configured to open.
