<p>PROBLEM TO BE SOLVED: To provide a liquid jet head and a liquid jet device capable of improving jet property of liquid by suppressing unevenness of pressure of liquid to be supplied from multiple liquid flow paths having different length, and increasing degree of freedom in design of the liquid flow paths.SOLUTION: A liquid supply member 30 includes: a flow path forming member 50 including multiple groove parts 51 for flow paths having different length, each made to communicate with each filter chamber 44; a flexible member 60 for sealing openings of the groove parts 51 for flow paths, and forming liquid flow paths 53; a pressure receiving part forming plate 70 disposed at the flow path forming member 50 so that an opening part 71 formed for each liquid flow path 53 faces each liquid flow path 53; and valve bodies 90 each energized by a coil spring 94 so as to close each liquid flow path 53, for opening the liquid flow path 53 against the energization force of the coil spring 94, by displacement of a pressure receiving part 72 based on pressure fluctuation in the liquid flow path 53. The respective opening parts 71 of the pressure receiving part forming plate 70 are formed in the same shape.</p> |
