To obtain a sheet with braille mark, which is easily manufactured and has high durability, by a method wherein a sheet-like base material and braille points are integrally formed out of a photo-setting resin by means of a stereo-lithographic method.
A sheet 10 with braille mark consists of a sheet-like base material 12 and braille points 14 formed on the surface of the sheet-like base material 12, all of which are integrally formed out of a same photo-setting resin by means of a stereo-lithographic method. Since a resin cured layer formed by the stereo-lithographic method is very thin, a highly accurate forming is carried out. Thus, both the sheet-like base material 12 and the brailles points 14 formed on the surface of the base material can also automatically be formed with enough accuracy. In addition, the sheet-like base material 12 and the brailles points 14 can be integrally and continuously formed in a tank, in which the same photo-setting resin liquid is filled. Further, since the sheet-like base material 12 and the braille points 14 are integrally and continuously formed out of the same photo-setting resin, no braille points 14 separate from the sheet- like base material.
