Abstract
A liquid jet head includes a piezoeletric body substrate and an opaque substrate bonded to the piezoelectric body substrate. The piezoeletric body substrate has ejection grooves arrayed with an identical pitch P in a reference direction and non-ejection grooves arrayed alternately with the ejection grooves while shifted from the ejection grooves by a half pitch (P/2). The opaque substrate has through holes arrayed in the reference direction. The through holes include a row of through holes corresponding in number to and communicating with the respective ejection grooves, a first through hole arranged outside of one end side of the row of through holes so that it does not communicate with any of the ejection grooves, and a second through hole arranged outside of another end side of the row of through holes so that it does not communicate with any of the ejection grooves.
