PROBLEM TO BE SOLVED: To manufacture a Braille plate hardly collapsing the convex parts for the Braille and having a long life span. SOLUTION: A punch 11 for forming Braille, a dice 21, and a supplying mechanism for supplying a steel ball B in front of the punch 11 at every operation stroke of the punch 11 are combined with each other. The punch 11 can form the Braille plate P by burying the steel ball B into a projecting part Pa1 of the plate main body Pa from the back, and since the projecting part Pa1 of the Braille plate P is reinforced through the steel ball B, the projecting part Pa1 is hardly collapsed at the using time.
