Liquid jet head and liquid jet apparatus

Abstract

A liquid jet head includes a piezoelectric body substrate including a plurality of groove arrays in which a long and narrow ejection groove and a long and narrow non-ejection groove are alternately arrayed in a reference direction. The other side end portion of the ejection groove included in a one side groove array, and a one side end portion of the non-ejection groove included in the other side groove array do not overlap in a thickness direction of the piezoelectric body substrate, and the other side end portion of the ejection groove included in the one side groove array, and a one side end portion of the ejection groove included in the other side groove array communicate, or overlap in the reference direction, of adjacent groove arrays.

Dependencies are inferred from the claim text.
