Ink jet head and a method of manufacturing thereof.

摘要

A casing (25) and a nozzle plate (27) form a hollow cavity in which ink liquid can be filled. A buckling structure body (21) is disposed within this hollow cavity. A nozzle orifice (27a) is provided in a nozzle plate (27) at a position corresponding to the buckling structure body (21). The buckling structure body (21) has a portion extending in a longitudinal direction (in the direction of arrow D2). Both ends of the buckling structure body (21) in the longitudinal direction are fixedly attached to the casing (25) via an insulative member (23). The buckling structure body (21) is formed of a material that is displaced at least in the longitudinal direction by conduction of current from a power source (29). Thus, an ink jet head of a long lifetime is provided that can provide a great discharge force while maintaining its small dimension. <IMAGE>
