    摘要： A method of fabricating a liquid ejection head is provided. The method includes preparing a first die including projected streak portions aligned in parallel by a predetermined pitch and gap portions formed between the adjacent projected streak portions. The first die is adapted to form groove-like recess portions by pressing the projected streak portions to a metal plate. The method further includes preparing a second die for supporting the metal plate to which the projected streak portions of the first die are pressed. Each of the projected streak portions includes: an inner wall forming portion for forming an inner wall of the corresponding groove-like recess portion extending in a depth direction of the corresponding groove-like recess portion; a connecting face portion; and an inclined face portion, continuous via the connecting face portion to the inner wall forming portion, for forming a bottom portion of the corresponding groove-like recess portion into a substantially V-like shape.

    摘要： A punching apparatus forms a hole at a bottom portion of each of recesses which are formed in a metal plate in advance and arrayed in a first direction. A female die supports the metal plate. A male die is opposed to the recess and provided with a punch array in which a plurality of punches in the first direction. The male die is movable in a second direction perpendicular to the first direction to form the hole with each of the punches. The punches include first punches each having a distal end face which is slant in the second direction. A slant angle of the distal end face corresponds to a warp of the plate member due to the formation of the recesses.
