PROBLEM TO BE SOLVED: To provide a magnetic treatment device in which a magnetic through-hole which one end of the iron core of a coil enters is covered by a cover sheet with a substantially flat rear face and, the one end of the iron core is allowed to come close to the cover sheet, to thereby make "improvement of the magnetic efficiency" compatible with "maintaining of case strength" and to further achieve "improvement of manufacturing efficiency."SOLUTION: A magnetic treatment device comprises: a case body 2 carrying a magnetic action surface 2a; and a cylindrical coil 3 contained in the case body 2. One end part 7a of the iron core 7 protrudes from one end side 4a of the coil 3. The one end part 7a of the iron core 7 enters a magnetic through-hole 8 from its inner surface opening 8b, the magnetic through-hole 8 passing through the magnetic action surface 2a side of the case body 2 in a thickness direction. A substantially flat cover sheet 16 of a rear face 16a on the case body 2 side covers an outer surface opening 8c of the magnetic through-hole 8, and the tip of the one end part 7a of the iron core 7 comes close to the cover sheet 16. |
