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