Abstract
A liquid jet head has an actuator with grooves arranged on a surface of a substrate. The actuator is configured to discharge liquid from nozzles communicating with respective ones of the grooves. A flow path member supplies the liquid to the grooves of the actuator. A damper member is provided between the actuator and the flow path member for coupling the actuator and the flow path member to each other. The damper member is bonded with an adhesive to each of the actuator and the flow path member.
