A medical tool position-confirming system is provided with a medical tool 1 capable of emitting light, the medical tool 1 including a luminescent agent emitting near infrared fluorescence when irradiated with near infrared light having a wavelength within the range of 600 to 1400 nm, the luminescent agent being applied on a surface of the medical tool or kneaded into the medical tool, a light source 3 for directing the near infrared light 2 toward the medical tool 1, a camera 4 for receiving the near infrared fluorescence emitted from the luminescent agent of the medical tool 1, and a monitor 6 for displaying an image 5 taken by the camera 4. The position of the medical tool such as a shunt tube can be confirmed without using an X-ray.
