PROBLEM TO BE SOLVED: To provide a nutriment feeding tube wherein it is surely confirmed that the tip end of the nutriment feeding tube reaches in the stomach. SOLUTION: The nutriment feeding tube includes a tube body 2 and an inserting thin string 3 freely insertable into the tube body 2. On the tip end of the inserting thin string 3, a metal part 4 which is discolored by the gastric juice is attached. When the tube body 2 is inserted into the stomach 5b and then the inserting thin string 3 is pulled out from the tube body 2, if the metal part 4 at the tip end is discolored, it is confirmed that the tube body 2 is inserted into the stomach 5b.
