Filed: 1988-10-31
Abstract: PURPOSE:To simplify and reduce manufacturing steps, and to obtain a recording head having high reliability by providing a first board formed with discharge energy generator, and a second board integrally having a groove for forming a recording liquid passage and a discharge port forming member reduced in thickness at the discharge forming part. CONSTITUTION:A recording head is formed of a heater board 100 formed with a heater and wirings, and a ceiling plate 400 formed with a partition wall for limiting an ink passage and a common liquid chamber, etc., and integrally has a resin orifice plate 404. When the plate 404 is radiated with a laser light from an excimer laser oscillator 450 through a mask 453 formed with a rectangular hole, a thin groovelike part 465 is formed. Then, it is replaced with a mask having a hole corresponding to the orifice, radiated with the laser to form an orifice 466. The board 100 adheres to the plate 404 to obtain a recording head. Thus, there is no apprehension of closure of the orifice and the ink passage for facilitating overall positioning and assembling.
