ABSTRACT:
A stamp unit 1 is formed so that the circumference of the stamp material 3 is made as a slant surface 83 by heat-pressing both the lower end 4a of the holder 4 and the circumference of the stamp material 3. The lower end 4a of the holder 4 is formed in a wedge 82 so as to hook the circumference of the stamp material 3. Thereby the stamp material 3 can be surely retained to the holder 4, and the stamp material 3 and the holder 4 can be firmly sealed. As a result, stamping durability is remarkably improved when many stamping operations are repeated.
