US Patent 7780265 Ink-jet head and method of manufacturing the same

An ink-jet head includes a flexible print cable (FPC) supplying a driving signal to an actuator unit. The actuator unit has a piezoelectric member, an inner electrode, individual electrodes formed on a surface of the piezoelectric member, a first surface terminal and second surface terminals. A partial area of the FPC confronts the surface of the piezoelectric member and an adjacent area continuous to the partial area extends in a direction away from the surface of the piezoelectric member. A distance between an end of the surface of the piezoelectric member closest to the adjacent area and the first surface terminal is equal to or greater than a distance between the end surface of the piezoelectric member and the second surface terminal disposed closest thereto. The FPC is adhered proximate the end of the piezoelectric member via a thermosetting adhesive.
