Abstract
A magnetic sticking sheet comprising a non-magnetic base and a magnetic layer formed on the non-magnetic base by coating a magnetic coating material containing ferromagnetic particles and a binder, the magnetic layer having a thickness of 0.03 to 0.10 mm, oriented longitudinally to give a squareness ratio of 80 to 90%, and multipolar-magnetized longitudinally; the sheet having a total thickness of 0.08 to 0.25 mm and flexibility for rolling; the magnetic layer having a surface magnetic flux density of 35 to 100G; and the sheet having a magnetic sticking force, required for removing a magnetic sticking sheet fixed magnetically on a magnetic surface via the magnetic layer while keeping the magnetic surface and the sheet parallel, of 0.4 to 0.9 gf/cm2.
