Abstract

PURPOSE: To form the taped shape of an orifice so as to narrow its jet-out side and to sufficiently and stably obtain a necessary amount of ink drops for recording and a jet-out speed by forming the orifice in such a way that excimer laser beams are projected on a root and an orifice forming member from the recessed part forming an ink channel after they are integrally formed.
CONSTITUTION: In a die, the ink jet recording head is.molded without possessing the orifice 11. A laser device irradiates excimer laser beams 2 at a position where the orifice is formed from the ink channel side of an orifice plate 10, and the resin is removed and evaporated to form the orifice 11. The excimer laser beams 2 are projected on the plate 10 from the ink channel side 14 via a mask 4. The excimer laser beams 2 are converged by tilting one side θ1=2° with respect to an optical axis 13, and are projected in the direction perpendicular to the orifice plate 10 by tilting the optical axis 13 by θ2=10°. Thus, the laser beams are projected from the ink channel side, whereby the cross-sectional area of the orifice of a tapered shape shrinks in the jet-out direction.
