Abstract
Head chips, liquid jet heads, and liquid jet recording devices capable of effectively transferring the elastic energy to ink in ejection channels to obtain desired ejection performance are provided. A head chip includes an actuator plate in which jet channels and non-jet channels are alternately arranged, a side-surface common electrode formed on inner side surfaces opposed to each other in a second direction out of inner surfaces of the jet channel, a bottom-surface common electrode formed on a bottom surface facing to a first side in a thickness direction out of the inner surfaces of the jet channel, a first individual electrode formed on inner side surfaces opposed to each other in the second direction out of inner surfaces of the non-jet channel, and a second individual electrode disposed on an opposite surface facing to a second side in the thickness direction out of the actuator plate.
