Patent ID: 8622519

Claim:
An inkjet head, comprising: a head chip, wherein drive walls configured with piezoelectric elements and channels are arranged in parallel alternately, an outlet port and an inlet port of each channel are provided on a front surface and a rear surface of the head chip, respectively, and a drive electrode is formed on a surface of each drive wall inside the channel, so as to eject ink in the channel from a nozzle disposed on the front surface of the head chip by deforming the drive wall by applying voltage to the drive electrode, wherein a groove is formed along an array direction of the channel on an area of the rear surface of the head chip where the channel is not formed, a lead-out electrode electrically connected with the drive electrode is formed from the rear surface of the head chip to an inside of the groove, and by inserting an end of a wiring member, provided with a connection wiring corresponding to the lead-out electrode on an insulation member, into the groove, the connection wiring in the groove is electrically connected with the lead-out electrode so as to electrically connect the drive electrode with the connection wiring via the lead-out electrode, and wherein the wiring member contacts a lead-out electrode side in the groove with contact pressure via a filling member provided at an opposite surface side to a connection wiring forming surface of the wiring member so as to electrically connect the connection wiring with the lead-out electrode.
