Abstract:
1. A liquid jet head chip, comprising: a jet plate having a plurality of jet holes for jetting liquid; a liquid feeding portion comprising first and second actuator plates each having a plurality of partitions spaced apart from one another to form groove portions extending in a direction perpendicular to an arrangement direction of the jet holes, the first and second actuator plates being superimposed relative one another so that the partitions of the first actuator plate extend into the respective groove portions of the second actuator plate and so that the partitions of the second actuator plate extend into the respective groove portions of the first actuator plate to thereby form a plurality of channels communicating with the jet holes for supplying liquid from the channels to the jet holes, first electrodes configured to be driven by a drive voltage applied by a driving circuit and formed on only one of upper half portions and lower half portions of the respective partitions of the first actuator plate, second electrodes configured to be driven by a drive voltage applied by the driving circuit and formed on only the other of the upper half portions and lower half portions of the respective partitions of the second plate, and first and second flexible circuit boards connected to the first and second electrodes, respectively, for electrically connecting the first and second electrodes and the driving circuit to each other; and a sealing compound made of an insulating material and disposed on rear end sides of the first and second actuator plates.
