Magnetic sticking sheet and method of producing same

A method of producing a magnetic sticking sheet comprising the steps of:

• coating on a non-magnetic base a magnetic coating material comprised of ferromagnetic particles dispersed in binder to form a coated film;
• orienting an axis of easy magnetization of the ferromagnetic particles in a parallel direction to the coated film by applying a magnetic field;
• drying the coated film while orienting the axis of easy magnetization by drying in the magnetic field to obtain a squareness ratio of 80 to 90% in the parallel direction to the coated film;
• further drying the coated film to form a magnetic layer;
• and
• multipolar-magnetizing the magnetic layer as the magnetization inverts alternately in the parallel direction to the magnetic layer,
• the step of multipolar-magnetization including the step of placing a combined permanent magnet comprised of a plurality of magnets stacked facing each other with different magnetic poles so as to face at least a side of the magnetic sticking sheet where the magnetic layer is formed.
