Abstract
Official abstract text for this publication.
A liquid droplet ejection head includes plural nozzles; plural individual liquid chambers; a common liquid chamber supplying liquid to the plural individual liquid chambers; a filter sheet member including plural pores formed therein to filter the liquid; and a frame body including an opening part and being in connection with the filter sheet member with adhesive. Further, a size of a region where the plural pores are formed is greater than the opening part of the frame body; an adhesive accumulation area is formed on an inner peripheral end of the opening part; and a size of the adhesive accumulation area in a protruding direction of the adhesive is greater than a size of an area between adjacent pores in the filter sheet member.
