Liquid ejection head and liquid ejection apparatus
A liquid ejection head includes a supply manifold, a return manifold, and individual channels each connected, at its upstream end, to the supply manifold and, at its downstream end, to the return manifold. Each of the individual channels communicates with a corresponding one of nozzles arranged in an array on a nozzle surface. The supply manifold and the return manifold extend in an extending direction along the nozzle array. The return manifold includes a lower portion located below the supply manifold to overlap the supply manifold in plan view orthogonal to the nozzle surface, and a standing portion located at at least one of opposite ends of the lower portion in the extending direction to be outside the supply manifold in plan view. The standing portion has a height to cover at least a portion of an end of the supply manifold when viewed in the extending direction.
