This invention makes it easy to operate for a medical appliance to be retained in a human body. The magnetic cap (10) includes an annular magnet (2) secured to an upper face of a connecting plug body (1); a disk like magnet (4) secured to an upper face of a lid body which is detachably coupled to the connecting body (1) through a flexible band (6); and a strap (5) attached to an end of the lid body (3). The magnets (2) and (4) are set to be 5 to 15 mm in diameter, 0.5 to 5.0 mm in thickness, and 1500 to 2000 gauss in magnetic flux density. Magnetic poles on contact faces of the magnets (2) and (4) are directed in opposition to each other. |
