The die includes a die base, a die body, and an opening/closing member. In the die base, a storage portion for storing refrigerant is formed. The die body includes a mounting surface, a forming surface, and a plurality of flow channels. The mounting surface is located on the storage portion side of the die base. The forming surface is located on the opposite side of the mounting surface. The flow channels pass through the die body from the mounting surface to the forming surface. The opening/closing member is disposed between the die base and the die body. The opening/closing member includes a plurality of through holes corresponding to the plurality of flow channels. The opening/closing member is configured to be movable with respect to the die base and the die body such that each of the through holes brings the corresponding flow channel and the storage portion into communication.
