PROBLEM TO BE SOLVED: To provide a fine ceramic magnet of neodymium and samarium which is magnetized after performing kneading, molding, glazing, forming a magnetic field, baking, sintering, and aging treatment on magnetic material powder obtained by adding monazite powder to magnetic material powder of samarium and neodymium and the magnetic material powder, and body powder or the material powder which is obtained by adding infrared radiative material powder to porcelaneous body powder or the material powder and the body powder or the material powder. SOLUTION: A magnetic material of samarium and neodymium is used as a principle material, porcelaneous body powder or the material is used as a sub-material, and a radioactive material (monazite) and an infrared radiative material (zirconia) are used as auxiliary materials. After the steps of kneading, molding, glazing, forming a magnetic field, baking, sintering, aging treatment, and magnetization, a fine ceramic magnetic of neodymium and samarium is obtained which radiates infrared rays and negative ions.
