To provide a separating face capable of forming a precise outline at the time when a joined part is cut.

A stamp die 6 and a punch ram 7 mutually joined only through an extremely thin joining part 4 are formed by integrally forming two members 2 and 3 of a medium dispenser at first by integrally jet molding a plastic material. The member 3 forming a ram 7 is linearly moved in the direction 12 by applying pressure load and fitted in the other member 2. Consequently, a joined part 4 is cut in the same manner as the shearing manner. As a result, while being provided with the same quality, both of the member 2 and 3 are remarkably easily manufactured from the same material quality.
