The die body (11) includes a mounting surface (112), a forming surface (111), and a plurality of flow channels (113). The mounting surface (112) is located on the storage portion (122) side of the die base (12). The forming surface (111) is located on the opposite side of the mounting surface (112). The plurality of flow channels (113) pass through the die body (11) from the mounting surface (112) to the forming surface (111). The opening/closing member (13) is disposed between the die base (12) and the die body (11). The opening/closing member (13) includes a plurality of through holes (131) corresponding to the plurality of flow channels (113). The opening/closing member (13) is configured to be movable with respect to the die base (12) and the die body (11) such that each of the through holes (131) brings the corresponding flow channel (113) and the storage portion (122) into communication.
