An ink-jet head includes a head main body including a channel unit in which a pressure chamber is formed, and a piezoelectric actuator having a piezoelectric deformation portion facing the pressure chamber, and an FPC which has a substrate and a plurality of wires, and which is arrange on an upper side of the piezoelectric actuator. A plurality of projections bent to form a projection toward the head main body is formed in the FPC. A front end of the projections is in contact with an area not facing the pressure chamber, on a surface of the piezoelectric actuator. Accordingly, it is possible to suppress hindering of a deformation of the piezoelectric deformation portion accompanied by a liquid discharge, due to a contact with a flexible flat cable.
