PROBLEM TO BE SOLVED: To provide a method and a device for producing a remelted raw material where fine crushed matters suitable for remelting can be made, thus troublesome cutting operation is not required, further, neither reduction of a yield nor rise of cost due to cutting operation is caused, and, even in the case they include a high melting point material or a high vapor pressure material, among the obtained crushed matters, the ones having a nearly uniform composition can be obtained. SOLUTION: When a remelted raw material is produced by vacuum-sucking molten metal floated and melted in a cold crucible furnace into a mold and solidifying the same, the molten metal is vacuum-sucked into the mold at which a plurality of mutually communicating small chambers are formed at the inside, and is solidified.
