摘要：
In a capsule medical apparatus guidance system (11) that includes a capsule body (2) that is inserted into a subject (1) together with a liquid introduced into the subject (1), includes a permanent magnet, and performs, in the liquid, examination or treatment of the interior of the subject1 and a magnetic field generation device (20) that is provided outside the subject (1), generates a magnetic attraction on the permanent magnet, and guides the capsule body (2), a mass of the capsule body (2) excluding the permanent magnet is less than a product of a volume of the capsule body (2) and a density of the liquid, and the magnetic field generation device (20) guides the capsule body (2) while a maximum value of a magnetic attraction that the magnetic field generation device (20) generates vertically upward on the capsule body (2) is equal to a maximum value of a magnetic attraction that the magnetic field generation device (20) generates vertically downward on the capsule body (2) and the maximum value of the magnetic attraction that is generated vertically upward or downward is less than a value that is obtained by multiplying a mass of the permanent magnet by a gravitational acceleration.
