<p><P>PROBLEM TO BE SOLVED: To provide a liquid ejection head whose width is made small, when pressuring chambers are arranged in a grid shape, and a recorder using the same. <P>SOLUTION: The liquid ejection head 2 includes a flow path member 4 having a plurality of ejection holes 8, a plurality of pressuring chambers and n (n is an even number≥4) pieces of manifolds 5b, and a plurality of pressuring parts 30. In the plan view of the flow path member 4, the pressuring chambers 10 are arranged in the grid shape where they are arranged in a row direction and a column direction, the plurality of manifolds 5b extend from one end side to the other end side of the flow path member in the row direction, and a first partition 15a narrower than the manifold 5b and a second partition 15b wider than the manifold 5b are provided as a partition between the manifolds 5b. Then, ejection holes 8 connected from the adjacent manifold 5b form two ejection hole rows 9 on the respective partitions, and the respective ejection holes 8 are arranged to satisfy a predetermined condition. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
