ABSTRACT:
The present invention includes a step of cooling a molten metal within a fine space present in the inside of an object and hardening it while applying a forced external force exceeding atmospheric pressure to the molten metal. The fine space is opened on the outer surface of the object in terms of one end thereof. The forced external force is given by at least one member selected among a pressing pressure, an injection pressure and a rolling compaction and applied to the molten metal from the opening surface side on which the fine space is opened, in a state that the other end side of the fine space is closed.
