PROBLEM TO BE SOLVED: To provide an apparatus for discharging molten metal, which apparatus can quickly discharge a required amount of solder on the land of a printed circuit board, etc. , and is excellent in the productivity. SOLUTION: The apparatus for discharging molten metal stores the molten metal in a storage chamber having a plurality of nozzle holes, and discharges the liquid droplets of the molten metal from a plurality of the nozzle holes, and integrates the liquid droplets by making them collide with each other during flying. As a result, it is possible to provide a molten metal discharging means capable of flying the liquid droplets of the molten metal having the amount according to the number of the nozzle holes, and to efficiently form the large diameter solder bump having a required amount.
