Patent ID: 10259215

Abstract:
Provided are a liquid jet head with which the size-reduction can be achieved, while the resistance of wiring formed on a wiring plate such as a sealing plate is lowered, and a method for manufacturing the liquid jet head. The liquid jet head includes: a sealing plate 33 having a first surface 41 to which a pressure chamber-forming plate 29 including multiple piezoelectric elements 32 is joined and a second surface 42 which is on a side opposite from the first surface 41 and to which a drive IC 34 that outputs signals for driving the piezoelectric elements 32 is joined, wherein a lower surface-side embedded wire 51 connected to a common wire 38 common to the driving elements 32 are formed on the first surface 41 of the sealing plate 33, and the lower surface-side embedded wire 51 is at least partially embedded in the sealing plate 33.
