<P>PROBLEM TO BE SOLVED: To provide a droplet ejection apparatus for reducing the flexibility of a cover member to a well-known limit or lower, increasing nozzle density in a printing direction, and increasing the printing speed of a print head. <P>SOLUTION: The droplet deposition apparatus includes an array of a plurality of fluid chambers defined by a pair of opposing chamber walls separated from each other at a chamber wall interval, and in fluid communication with a nozzle for droplet ejection therefrom; and a cover member that is joined to edges of the chamber walls and thus seals one side of the chambers. The cover member has a ratio of a cover thickness to a chamber wall interval smaller than or equal to 1: 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
