PROBLEM TO BE SOLVED: To provide a liquid jet head capable of quickly discharging bubbles out of a flow channel.SOLUTION: A liquid jet head has a configuration laminating plural substrates including a nozzle substrate in which the liquid jet nozzles are formed, and a flow channel guiding a liquid to the nozzle is formed at least a part of plural substrates. The flow channel includes: a first flow path 24 extending in the X direction crossing with a laminating direction in which plural substrates are laminated; a bending part 26 crossing with the X direction and bending in the Z direction having a component in the laminating direction; and a second flow path 25 extending from the bending part 26 to the Z direction. In the inside of the flow path, a wall 54 crossing with both X and Z directions is provided at a corner part 53 of the bending part 26 pinched between the inner walls 51 and 52 of the first and second flow paths 24 and 25.SELECTED DRAWING: Figure 4 |
