A liquid jet head chip has a jet plate with jet holes for jetting liquid. A piezoelectric actuator has first and second actuator plates superimposed over one another to form channels communicating with the jet holes. The first actuator plate has first partitions spaced apart from one another to form first groove portions and has first electrodes each disposed on only a portion of a side surface of a respective one of the first partitions. The second actuator plate has second partitions spaced apart from one another to form second groove portions and has second electrodes each disposed on only a portion of a side surface of a respective one of the second partitions. The first partitions of the first actuator plate extend into respective second groove portions of the second actuator plate, and the second partitions of the second actuator plate extend into respective first groove portions of the first actuator plate to form the channels communicating with the jet holes.
