A system for guiding capsule medical device is provided with a capsule medical device, a magnetic guidance device, and an image display device. The capsule medical device is provided with an imaging unit for imaging an in-vivo image of a subject and a permanent magnet magnetized in a known direction relatively fixed with respect to an upward and downward direction of an imaging surface of the imaging unit in a capsule casing, and has a center of gravity at a location deviated from a geometric center of the capsule casing in a direction parallel to a plane parallel to a magnetization direction of the permanent magnet and an imaging direction of the imaging unit and different from the magnetization direction of the permanent magnet, and maintains a specific state in which the magnetization direction of the permanent magnet and the imaging direction of the imaging unit are parallel to a vertical plane in liquid introduced into the subject. The magnetic guidance device magnetically guides the capsule medical device in the liquid while maintaining the specific state by applying a magnetic field to the permanent magnet. The image display device displays the in-vivo image by conforming a direction of intersection line of the imaging surface and the vertical plane in the in-vivo image to an upward and downward direction of the display screen.
