<p><P>PROBLEM TO BE SOLVED: To provide a liquid droplet discharge head capable of surely defoaming a liquid, even when treating various kinds of liquids. <P>SOLUTION: The liquid drop head discharge head (1) comprises a substrate (10) formed with a plurality of flow paths 14; a plurality of pressure chambers (34) communicating, with each flow path (14) being respectively provided with one side of the substrate (10); a droplet discharge part (30) for discharging the liquid supplied to the pressure chambers (34) as droplets; and the liquid accommodation part (20), provided with the plurality of accommodation spaces (24) capable of communicating with each flow path provided on the other side of the substrate (10), where the number of flow paths and the number of pressure chambers are the same, and the number of accommodation spaces are provided with integral times of the number of flow paths. The liquid accommodation parts are made variable with respect to the substrate relatively so as to change the accommodation space that communicates with the flow paths. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
