Abstract
In a liquid ejection head and a liquid ejection apparatus that can suppress deterioration of image quality, a plurality of second beam-shaped members is provided on the downstream side of a first beam-shaped member in a flow passage connected to an ejection element substrate. The first beam-shaped member divides the flow passage into two flow passages in a liquid-flowing direction and the second beam-shaped members sandwich a line extending from the first beam-shaped member in the liquid-flowing direction.
