Abstract: PROBLEM TO BE SOLVED: To prevent a punched sheet material from being pushed in push-cutting blades to clog there in a sheet-like die (a flexible die) which is used for push- cutting a sheet to be worked along a prescribed border line and punching the part surrounded by the border line. SOLUTION: One side of a sheet-like die 21 is painted first with a photo-resist 22 and then with a photo-mask 22 before sensitization. A light transmitting part 24 having a wide width, is formed along a border line, which forms a push-cutting blade of the photo-mask 23, while other light transmitting parts 25...25 having a narrow with are formed inside the border line. By using this, the resist, which was hardened by sensitization, is given a wide part 26 and a narrow part 27. After the etching in a prescribed time, a high-mountained push-cutting blade 28 is formed in the wide part, while a low-mountained rejecting part 29 is formed in the narrow part. This rejecting part 29 prevents the punched sheet from being pushed in the push-cutting blades 28.
