Zusammenfassung:	PURPOSE:To enable information to be written easily and stably without any discoloration and smear by applying a ferrite paint with a thermo-setting resin such as epoxy resin as a binder onto a printed-wiring board, heating and curing it, and then forming a magnetized stripe. CONSTITUTION:Ferrite paint is applied onto a printed-wiring board 4 consisting of an insulating board 2 where a wiring pattern 1 is formed and a solder resist 3 which is a surface protection film when performing soldering, for example, in band shape and then it is heated and cured for forming a magnetic stripe 5, where a thermo-setting resin such as epoxy resin, phenol, and polyimide is used as the ferrite paint and a ferrite having a Curie point exceeding the maximum temperature on assembly is used.
