<p>PURPOSE: To prevent a strong rare-earth magnet from coming off from the surface of a steel plate, etc., and to prevent the user of a medical treatment device from having eruptions on his skin due to the device by coating the magnet with a resin in a sandwich-like state. CONSTITUTION: Recessed sections 4 and 4 respectively having sizes which are sufficient to house a rare-earth magnet 1 and depths which are nearly equal to the half of the thickness of the magnet 1 are respectively formed on the facing surfaces of discoid synthetic resin plates 2 and 3 which are provided on the top and bottom of a resin-coated magnet 5. The magnet 5 is formed by sticking the resin bodies 2 and 3 to each other in a sandwich-like state after putting the magnet 1 in the recessed sections 4 and 4. Or, the resin-coated magnet 5 is formed by forming a through hole 6 having a size which is sufficient to house the magnet 1 through a discoid synthetic resin plate 3 having a thickness which is nearly equal to that of the magnet 1 and putting the magnet 1 in the hole 6 of the resin plate 3, and then, sticking thin discoid synthetic resin plates 2 and 2 of the same resin to the upper and lower surfaces of the resin plate 3.</p> |
