<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid ejection head and the liquid ejection head, capable of suppressing defective operation of a piezoelectric element, which may be caused when a plating method is employed for formation of a wiring part. <P>SOLUTION: The inkjet type recording head includes: the piezoelectric element 300 for displacing a pressure generating chamber communicating with a nozzle for ejecting ink; and a lead electrode 90 which is partially run over the piezoelectric element 300 and is electrically connected with the piezoelectric element 300 wherein the lead electrode 90 has a first electrically conductive layer 121 and a second electrically conductive layer 122 which is formed by the plating method and covers the first electrically conductive layer 121. The method of manufacturing the inkjet type recording head includes an oxide film forming process for forming an oxide film 131 having electrical conductivity on the running-over surface 130a of the piezoelectric element 300 to which the lead electrode 90 is connected, before forming the second electrically conductive layer 122 by the plating method. <P>COPYRIGHT: (C)2013,JPO&INPIT |
