An apparatus is provided that forms embossed portions on a workpiece. The
apparatus includes a melting chamber filled with melt, such as ceramic,
nozzles provided at a lower portion of the melting chamber, and presses
provided adjacent to each of the injection nozzles. The injection nozzles
drop the melt on the workpiece and the presses press the dropped melt
into a predetermined shape of the embossed portions in a state where the
dropped melt is being solidified after being dropped on the workpiece.
