<P>PROBLEM TO BE SOLVED: To provide an inkjet head which suppresses the deterioration of a piezoelectric body caused by moisture in the air and can be downsized even when a density is made higher, and to provide an inkjet recorder. <P>SOLUTION: The inkjet head 100 includes a liquid chamber 110 in which a space between a nozzle substrate 111 and a vibrating plate 112a is separated by a partition wall 112b. A piezoelectric element 120 is formed on the space separated by the partition wall 112b, of the vibrating plate 112a, a common electrode 121 is extended on the partition wall 112b, and an insulating film 132 is stacked on the vibrating plate 112a. Wiring 140 is pulled out onto an area including a part of the common electrode 121 from an individual electrode 123 through an opening 132a, an opening 133a through which the wiring 140 is pulled out is formed between the insulting film 132 and the area including the wiring 140, and an insulting film 134 in which a contact hole 134a is formed is formed on the wiring 140. The insulting films 133 and 134 are not present in the area excluding the area on the space separated by the partition wall 112b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
