Abstract
Provided are a liquid jet head and a liquid jet recording apparatus which are capable of improving ability to collect excess liquid to prevent contamination with excess liquid and which are capable of stabilizing jetting of liquid after the liquid is filled. A liquid jet head includes a nozzle guard (24) for covering a periphery of a nozzle column (31c), the nozzle guard having a slit (24c) formed therein which is opposed to the nozzle column (31c), and a suction flow path (15) connected to a suction pump for sucking excess ink which leaks from the nozzle column (31c), in which inside space of the nozzle guard (24) is partitioned into first space (S1) and second space (S2), and the first space (S1) and the second space (S2) communicate with each other via a communication hole group (31f) in a nozzle plate (31).
