摘要： The medical tube inserted into a body cavity of a patient includes a flexible tube and a magnet provided at the tip end portion of the tube for electromagnetically detecting the position of the tip end portion of the tube inserted in the body cavity, from outside the body. This magnet includes a plurality of magnet pieces arranged in the length direction of the tube to have a column-like shape as a whole. The direction of magnetic pole of the magnet is set to the length direction of the tube. Therefore, since the magnet is divided into a plurality of magnet pieces, even a magnet increased in size can be inserted smoothly into a body cavity of a patient.
