PROBLEM TO BE SOLVED: To provide a method capable of filling a fine space with a hardened metal without causing a gap or void; to provide a method capable of preventing unevenness of the hardened metal cooled in the fine space; and to provide a method capable of contributing to simplification of processes and improvement of yield. SOLUTION: The method for filling a molten metal 4 into a fine space 21 present in an object 2 to be processed and hardening the metal includes: the steps of filling the molten metal 4 from an opening surface opened on the fine space 21 into the inside, and cooling the molten metal 41 filled in the fine space 21 in a state that a forcible external force F1 exceeding atmospheric pressure is applied and hardening the molten metal.
