PROBLEM TO BE SOLVED: To provide a liquid jet head and a liquid jet device capable of preventing bubbles from retaining while securing a strength of members that form a liquid reservoir chamber.SOLUTION: A liquid jet head comprises: a liquid reservoir chamber accumulating ink to be supplied to a plurality of pressure chambers; a plurality of first beam-shaped parts Q1, which are disposed at intervals between respective adjacent ones in an X direction of alignment of plurality of the pressure chambers, and which protrude from an internal wall surface of the liquid reservoir chamber; and a plurality of second beam-shaped parts Q2, which are disposed at intervals between respective adjacent ones along the X direction, at positions different from those of the plurality of first beam-shaped parts Q1 in the X direction, and which protrude from the internal wall surface of the liquid reservoir chamber on a downstream side of the plurality of first beam-shaped parts Q1.SELECTED DRAWING: Figure 4 |
