Abstract
In order to manufacture a liquid ejection apparatus, a metal board is prepared. The metal board is subjected to a plastic working to form a plurality of recesses on a first face in a first region of the metal board. Through holes are punched so as to communicate the recesses and a second face of the metal board. The metal board is subjected to a plastic working to form a plurality of dents in a second region of the meal board. A metallic nozzle plate formed with nozzles is joined onto the second face of the metal board, such that each of the nozzles is communicated with one of the through holes.
