ABSTRACT:
A capsule medical apparatus inserted in the body cavity includes a spiral projected portion on the outer peripheral surface of a body cavity inserting portion. The pitch, height, and cross section of the projected portion and the like are set to have proper values and shapes suitable to the advance thereof. The body cavity inserting portion has a magnet. An external magnetic guiding device applies a rotating magnetic field to the magnet and the magnetic torque acts on a magnet for rotation. Thus, the medical apparatus stably advances.
