<P>PROBLEM TO BE SOLVED: To provide a liquid ejection head which cannot be in the condition that liquid is not ejected from a plurality of nozzles even when a large bubble is generated in a manifold. <P>SOLUTION: A liquid ejection head 1 includes a plurality of pressure generating chambers 5, nozzles 9 that communicate with respective pressure generating chambers 5, a manifold 7 that communicates with an opening 31 and serves as a common flow channel for the multiple pressure generating chambers 5, ink supply channels 10 having openings 32B that open into the manifold 7, that communicates between the manifold 7 and each pressure generating chamber 5, and supplies ink in the manifold 7 to each pressure generating chamber 5, and a piezoelectric vibrator 6 that causes ink to be ejected through each nozzle 9 by generating pressure within each pressure generating chamber 5. The ink supply opening 32B of at least one ink supply channel 10 among the ink supply channels 10 is formed in the inner surface of a recess 8 which has an opening 28B to the manifold 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
