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 having a first surface to which a pressure chamber-forming plate including multiple piezoelectric elements is joined and a second surface which is on a side opposite from the first surface and to which a drive IC that outputs signals for driving the piezoelectric elements is joined, wherein a lower surface-side embedded wire connected to a common wire common to the driving elements are formed on the first surface of the sealing plate, and the lower surface-side embedded wire is at least partially embedded in the sealing plate.
