Liquid jet head and liquid jet apparatus

A liquid jet head that pressurizes liquid and ejects the liquid through nozzles in a liquid ejecting direction, the liquid jet head comprising:

• a nozzle opening surface having first and second nozzle rows each having openings of the nozzles linearly aligned in plurality;
• first and second walls that are provided parallel to each other at first and second end sections of the nozzle opening surface, respectively, and that are perpendicular to the nozzle opening surface, and the first and second walls are aligned with the first and second nozzle rows, respectively;
• and
• first and second pressure chambers that are in communication with the nozzles of the first and second nozzle rows, respectively, for reserving the liquid to be pressurized, the first pressure chamber is provided next to the first wall, and the second pressure chamber is provided next to the second wall, wherein
• a lengthwise direction of the first and second pressure chambers is aligned to the liquid electing direction and is perpendicular to the nozzle opening surface, and
• the liquid pressurized in the first and second pressure chambers flows in the liquid electing direction along the first and second walls, respectively.
