To provide an adherend structure for a magnet which is considered in that, when a door, a partition or a wall is used as a substrate of an adherend of a magnet, a ferromagnetic substance plate (steel plate or the like) to be a surface material of the adherend is mainly provided with convenience such as ornamentation and provided with a function to be easily attached/detached without creasing, a surface is prevented from being recessed by an external force and further, deposition noise during use can also be reduced.

In an adherend 1A of a magnet, a band-like sheet-shaped magnet 3 of which the thickness is 0.3 to 1.0 mm, the width is 10 to 120 mm and the magnetic attraction strength with a ferromagnetic substance plate member (steel plate or the like) is 15 to 75 g/cm², is deposited to a substrate 2 such as a door by lamination or a magnetic attraction force while using an adhesive continuously in at least one direction around four sides of the substrate, or in a shape of a lattice or parallel lines. On a top face of the sheet-shaped magnet 3, a ferromagnetic substance plate member 4 to which a mounting material 5 is applied and of which the thickness of 0.2 to 0.5 mm, is magnetically attracted. The mounting material can also be mounted on both surfaces and a spacer can also be disposed between a plurality of band-like sheet-shaped magnets 3.
