ABSTRACT:
Provided are a liquid jet head capable of preventing occurrence of crosstalk and obtaining a stable liquid ejecting property and a liquid jet apparatus. Partitions11at both sides in a width direction of a pressure generating chamber12are provided so as to extend to the vicinity of an end of a reservoir portion32at the pressure generating chamber12side. Liquid supply paths14and communicating paths100are provided by being divided for each of the pressure generating chambers12by the partitions11(wall portions11a). Specifically, each of the liquid supply paths14communicates with the pressure generating chamber12and is formed to have a width smaller than that of the pressure generating chamber12, and each of the communicating paths100allows the liquid supply path14and a communicating portion13to communicate with each other and is formed to have a width larger than that of the liquid supply path14. Thus, occurrence of crosstalk can be prevented and a stable liquid ejecting property can be obtained.
