PROBLEM TO BE SOLVED: To provide a liquid jetting head capable of achieving miniaturization and reduction of the number of components. SOLUTION: The liquid jetting head includes: first and second piezoelectric elements 16A and 16B respectively changing the volumes of first and second pressure generating rooms; a common fixing member 33 arranged on the opposite side of the first and second pressure generating rooms of the piezoelectric elements 16A and 16B and joined with parts of the piezoelectric elements 16A and 16B; and a flexible signal line film 35 on which input terminals, through which driving signals for driving the piezoelectric elements 16A and 16B are fed from the outside, and output terminals for feeding the driving signals to the piezoelectric elements 16A and 16B, are formed. The signal line film 35 includes: a first wiring part 35A having an input terminal on one side face of the fixing member 33 and an output terminal for feeding the driving signal to the piezoelectric element 16A; and a second wiring part 35B making a detour to the other side face of the fixing member 33 from the first wiring part 35A and having an output terminal for feeding the driving signal to the second piezoelectric element 16B.
