A liquid jet head includes ejection channels which extend in a channel extending direction and are filled with ink, dummy channels which extend in the channel extending direction and are not filled with ink, and a nozzle plate which is laminated on an actuator plate and includes nozzle holes each communicating with the corresponding ejection channel at a central part in the channel extending direction of the ejection channel. The actuator plate includes a first channel row and a second channel row each of which includes the ejection channels and the dummy channels alternately arranged side by side in the X direction, the first and second channel rows being spaced apart in the channel extending direction. The ejection channel and the dummy channel are each symmetric with respect to a plane that passes through the center in the channel extending direction and perpendicular to the channel extending direction.

A manufacturing method of a liquid jet head includes: a groove formation step of forming ejection grooves and non-ejection grooves alternately in the upper surface of an actuator substrate; a cover plate processing step of forming a recessed portion in the upper surface of a cover plate and slits penetrating from the bottom surface of the recessed portion to the lower surface opposite to the upper surface; an electrode formation step of forming conductive films on the both side surfaces and front surface of the ejection grooves, the both side surfaces of the non-ejection grooves, the inner surfaces of the slits and the recessed portion, and the lower surface of the cover plate; and a substrate joining step of joining the lower surface of the cover plate to the upper surface of the actuator substrate so as to communicate the slits with the ejection grooves.


A nozzle plate including nozzle arrays with a plurality of nozzle holes, actuator plates to be filled with ink, and a nozzle guard provided so as to cover the nozzle plate for protecting the nozzle plate are included. The nozzle guard includes a frame body formed to surround a periphery of the nozzle plate, and a cover body that blocks an opening portion of the frame body and in which slits that expose the nozzle arrays is formed. The frame body and the cover body are configured separately from each other, and the frame body and the cover body respectively include joint portions to be joined to each other.

A carriage includes a base plate, a liquid jet head which includes a support plate attached to the base plate, a first engagement portion which is formed on one end in a Y direction of the support plate, and a fixing tool for positioning the support plate with respect to the base plate, the fixing tool being slidable in an X direction with respect to the base plate and engaged with the first engagement portion. The fixing tool allows movement in the Y direction of the first engagement portion with respect to the fixing tool, and restricts movement in the X direction of the first engagement portion and movement in the thickness direction of the base plate of the first engagement portion with respect to the fixing tool.


A liquid jet head according to the present invention includes a partition separating adjacent grooves, a lower substrate fixing a lower portion of the partition, and an upper substrate installed on an upper end surface of the partition, the partition including an electrode layer on a surface lower than the upper end surface, the electrode layer including an outer surface approximately perpendicular to the upper end surface, and the outer surface continuing to the upper end surface through a first convex curved surface curving outward.
