Head chip, liquid jet head, liquid jet recording device, and method of manufacturing the head chip

摘要

A head chip for a liquid jet recording device has a pair of piezoelectric elements that form a liquid jet channel therebetween, a common electrode formed on a surface of each piezoelectric element on the liquid jet channel side, and a drive electrode formed on an opposite surface of the piezoelectric element. A cover plate is joined so as to cover a common terminal connected to the common electrode, and an integrated wiring that integrates and electrically connects all of the common terminals is formed on a surface of the cover plate. The integrated wiring is connected to the common terminals through the contact plugs formed in through-holes of the cover plate. Integrated terminals connected to the integrated wiring and drive terminals connected to the drive electrodes are arranged in line at an end of an actuator plate.
