METHOD FOR MANUFACTURING INKJET RECORDING HEAD AND INKJET RECORDING HEAD

PROBLEM TO BE SOLVED: To provide a method for manufacturing an inkjet recording head, which is capable of stably applying ultraviolet ray to an ultraviolet curable sealing material.SOLUTION: The method for manufacturing an inkjet recording head includes: a step for preparing a supporting member 10 having a light guide member 13 which is ultraviolet transmissive; a step for connecting a recording element substrate 20 with an electrical wiring tape 30 in an electrical connecting portion 45; a step for applying an ultraviolet curable resin sealing material 40 to the electrical connecting portion 45; and a step for applying ultraviolet ray 51 to the ultraviolet curable resin sealing material 40 from multiple directions so that any portion of the ultraviolet curable resin sealing material 40 is not shielded by the electrical wiring tape 30 and the electrical connecting portion 45. A part of the ultraviolet ray 51 is applied through the light guide member 13 so that the ultraviolet ray 51 is not shielded by the electrical wiring tape 30 and the electrical connecting portion 45 in any portion of the ultraviolet curable resin sealing material 40.
