摘要：
Using a guidance system with a simple configuration, propulsive motion along a longitudinal direction and changing of the propulsion direction are easily performed with good precision and stability. There is provided a capsule-type medical apparatus which is inserted into the body of a subject and is guided by an external magnetic field, the capsule-type medical apparatus comprising: a substantially cylindrical capsule; a propulsion mechanism for converting rotary motion about a longitudinal axis R of the capsule into propulsive motion along the longitudinal axis R; a magnet accommodated inside the capsule and disposed in such a manner that the magnetic-pole direction thereof can be switched between a direction along the longitudinal axis R and a direction intersecting the longitudinal axis R; and a securing portion for securing the magnet to the capsule in each of the switched states of the magnetic-pole direction.
