PROBLEM TO BE SOLVED: To provide a liquid jet head and a liquid jet device capable of suppressing leakage of adhesive into space sealed by the adhesive and suppressing rupture of the adhesive of the space sealed by the adhesive.SOLUTION: A liquid jet head includes a channel member provided with a channel communicating with a nozzle opening 21 that jets liquid, and the channel member includes a plurality of laminated substrates adhesively bonded by adhesive. Concave portions 13, 14, and 33 are provided in the substrates around a space sealed by the adhesive adhesively bonding the substrates of the channel member. The concave portions 13, 14, and 33 are open to atmosphere on an opposite surface to a surface in which the nozzle opening 21 is formed in a laminating direction of the substrates. |
