A medical-device magnetic guiding position detecting system that can prevent a decrease in the strength of a position detecting magnetic field in an operating area of a medical device is provided. The medical-device magnetic guiding position detecting system includes a medical device that is disposed in the body of a subject and that includes at least one magnet and a circuit including an internal coil, a first magnetic field generating unit for generating a first magnetic field in the operating area of the medical device, position detecting means for detecting an induction magnetic field induced in the internal coil due to the first magnetic field, and at least one pair of opposing coils for generating a second magnetic field that acts on the at least one magnet. The opposing coils forming each of the at least one pair are independently driven.
