To provide a magnetic therapeutic instrument in the shape of a flexible body as a whole capable of producing an effect on a large area while inhibiting its magnetism from being focused on a determined region, and meanwhile applying sufficient magnetism to a region requiring the effect of the magnetic therapeutic device.

In a magnetic plate (1) with magnetic force, at least two magnetized bodies (2) with a magnetic flux density stronger than the magnetic plate (1) is embedded with a bag (3) covering the general shape thereof so that the magnetic poles thereof may be flush with the upper and bottom surfaces thereof.
