It has a disk shape.

[0007]

[Function] Since the top of each protrusion is hardened, the hardened portion of the protrusion is deformed by being inserted into the soft material portion against the load of the human body, and the distance between each permanent magnet and the human body is reduced. Get smaller. Further, since each permanent magnet is installed at a position lower than the hardening portion in the recess and is joined to the flexible material portion, the binding force between the permanent magnet and the cushion material is increased.

In the magnetic cushion sheet of the second aspect, at the installation position of the permanent magnet, the outer peripheral portion of the permanent magnet bites into the side wall of the recess, so that the coupling force between the cushion material and the permanent magnet is further increased.
