A drainage tube indwelling device for an endoscope is provided with a drainage tube formed of insulating material, a guide wire formed of electrically conductive material, a connector that connects the guide wire with a high-frequency power source, and a fixing device capable of fixing the drainage tube with respect to the guide wire. The drainage tube is longer than a length of a treatment insertion channel of the endoscope, and the guide wire is longer than the drainage tube. The guide wire is slidably inserted in the drainage tube so that a distal end portion of the guide wire can be protruded from a distal end of the drainage tube.
