LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS |
| 摘要 |
Provided are a liquid ejection head and a liquid ejection apparatus which make it possible to suppress deterioration of image quality. Therefore, a plurality of second beam-shaped members is provided on the downstream side of a first beam-shaped member which divides a flow passage connected to an ejection element substrate into two flow passages in a liquid-flowing direction so as to sandwich a line extending the first beam-shaped member in the liquid-flowing direction. |
