Abstract

A liquid ejection head includes pressure chambers arranged in a first direction, each pressure chamber storing liquid, pairs of upstream and downstream flow paths, each pair communicating with a corresponding one of the pressure chambers, an upstream common chamber communicating with the upstream flow paths, an upstream port communicating with the upstream common chamber, a downstream common chamber communicating with the downstream flow paths, a downstream port communicating with the downstream common chamber, a bypass flow path connected between, and communicating with, the upstream and downstream common chambers, a bypass resistance flow path that communicates with the bypass flow path, and one or more pressure dampers including a first damper region located upstream side of the bypass resistance flow path and a second damper region located downstream side of the bypass resistance flow path.
