PROBLEM TO BE SOLVED: To surely perform printing in a required range without entailing an increase of a manufacturing cost and to obtain free designs having a luxurious feel. SOLUTION: A boundary surface 4 is formed at a boundary between an outer circumference of a printing surface 2b and a non-printing surface 2c formed on a slope. The boundary surface 4 may be partly inked and is inconspicuous buffer area. The boundary surface 4 is a surface formed to a small and minute raised shape, a surface formed to a step shape or a surface formed to approximately 90°with the printing surface 2b. The ink is put on the printing surface 2b by padded key print, and thereby the printing surface is printed. The boundary surface 4 is covered with the ink up the middle of the ink layer 5. As a result, the remaining of the portion absent of printing due to a print gap does not occur on the printing surface 2b and the adhesion of the unnecessary ink on the non-printing surface 2c does not occur.
