Abstract
An production apparatus of a semi-solidified metal has a vessel and a cooling device. The vessel into which a liquid-state metal material M is poured has a hollow member which is opened in up and down directions, and a bottom member which can close the lower opening of the hollow member and can be separated from the hollow member. The cooling device can cool the bottom member more than the hollow member.
