Abstract
A magnet sheet 3 with a thickness of 0.05 to 0.15 mm is formed by molding a material obtained by adding magnetic particles to a synthetic resin material into a sheet and multiple pole magnetizing one surface of the sheet to form alternate N and S poles on that surface. A printing sheet 2 with a thickness of 0.05 to 0.15 mm, constituted by a paper sheet such as a high quality paper sheet or a coated paper sheet or a synthetic paper sheet or a synthetic resin film, is bonded to the non-magnetized surface of the magnet sheet 3. A magnet display sheet 1 , which has a thickness of 0.1 mm to 0.3 mm, is thus obtained, and it is capable of being printing on with a usual home or office copier or printer.
