<p>PROBLEM TO BE SOLVED: To provide a magnetic therapeutic apparatus capable of imparting an effective magnetic field even if a diameter of a magnet is small and imparting no foreign matter feeling when stuck to the human body. SOLUTION: The magnet composed of a spherical ferromagnetic alloy having a nano composite structure for mutually isolating individual fine particles of an aggregate of fine particles of the ferromagnetic alloy by a layer of a metallic oxide or a spotted material or a void, is fixed to a central part of an adhesive surface of a sheet having an adhesive layer on one surface. The spherical ferromagnetic alloy having this nano composite structure is obtained in such a way that a melted ferromagnetic alloy is supplied on a plate-like disk rotating at a high speed in a gas atmosphere composed of at least one kind of argon, oxygen, nitrogen, hydrogen and helium, and is scattered as a droplet by operating centrifugal force, and is rapidly cooled in the gas atmosphere, and is self- organized. Rare earth, iron and a boron alloy are desirable as the ferromagnetic alloy.</p> |
