To provide a liquid jetting head capable of preventing a short circuit of an electric circuit caused by the migration of a conductive bump.
The inkjet head 10 includes individual electrodes 66, a common electrode 68, a piezoelectric sheet 60, a plurality of individual electrode terminals 70a and 70b electrically communicating with the individual electrodes 66, respectively, and an actuator unit 16 having a common electrode terminal 72 electrically communicating with the common electrode 68. The individual electrode terminals 70a and 70b and the common electrode terminal 72 are arranged on the surface of the actuator unit 16. The conductive bump 74 is formed on the surface of each electrode terminal 70a and 70b. A migration-preventing part 82 composed of a material more hardly causing the migration than the conductive bump 74 and electrically communicating with the conductive bump 74 is arranged between the common electrode terminal, and the conductive bump 74 formed in the individual electrode terminal 70a in the vicinity of the common electrode terminal 72.
