摘要 An apparatus of fabricating a liquid ejection head is provided. The apparatus includes: a first die including projected streak portions aligned in parallel by a predetermined pitch and gap portions formed between the adjacent projected streak portions, wherein the first die is adapted to form the groove-like recess portions by pressing the projected streak portions to a metal plate; and 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.
