PROBLEM TO BE SOLVED: To reduce a thickness of a liquid jet head 1 having two nozzle columns, and reduce unevenness of discharge speed of a liquid droplet jetted from respective nozzles. SOLUTION: The liquid jet head 1 includes: an actuator chip 3 including a first actuator 2a and a second actuator 2b on one surface 4 side and another surface 5 side, respectively, of a substrate 12; a first flow path member 11a and a second flow path member 11b placed on both sides of the actuator chip 3; and a connecting member 14 for dividing and supplying liquid to the first flow path member 11a and the second flow path member 11b. The flow path members 11 include therein liquid supply chambers 9 which are elongated regions. Cross-sectional areas of the liquid supply chambers 9 in a direction orthogonal to the longitudinal direction thereof are formed to gradually decrease from a liquid inflow side to an opposite side thereof.
