Guidance apparatus and capsule medical apparatus guidance system

A guidance apparatus configured to guide a capsule medical apparatus that is introduced into a subject and that internally includes a magnet, by a magnetic field, the guidance apparatus comprising:

• a magnetic field generator configured to generate a magnetic field that acts on the magnet for guiding the capsule medical apparatus;
• a magnetic field shielding material configured to shield the magnetic field generated by the magnetic field generator;
• an operation input device configured to receive an input of at least one of a target position and a target posture for guiding a position and a posture of the capsule medical apparatus;
• and
• a controller configured to control the magnetic field generator to generate a magnetic field that has been corrected to offset or reduce a deviation amount of the position or the posture of the capsule medical apparatus with respect to the target position or the target posture, caused by distortion, due to the magnetic field shielding material, of a magnetic field for guiding the capsule medical apparatus to at least one of the target position and the target posture.
