<P>PROBLEM TO BE SOLVED: To provide a continuous type liquid ejection head that produces a droplet at a short distance, and can efficiently eject high-viscosity ink. <P>SOLUTION: The liquid ejection head includes an elastic body deformation unit 302 and an orifice plate 303, which are arranged adjacent to each other. The liquid ejection head ejects ink by periodically deforming an elastic body so as to periodically vary the opening area of an ejection opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
