Abstract

A liquid ejection head includes pressure chambers arranged in a first direction and 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, and a bypass flow path communicating with the upstream and downstream common chambers. Each of the upstream flow paths is inclined in a direction against a flow of the liquid in the upstream common chamber, and each of the downstream flow paths is inclined in a direction against a flow of the liquid in the downstream common chamber.
