Abstract

A liquid ejection head includes pressure chambers (42) arranged in a first direction and respectively communicating with nozzles, each pressure chamber for storing liquid, pairs of upstream and downstream flow paths (43, 46), each pair communicating with a pressure chamber, the upstream and downstream flow paths of each pair being connected to first and second ends of the corresponding pressure chamber, an upstream common chamber (44) communicating with the upstream flow paths, a downstream common chamber (47) communicating with the downstream flow paths, a bypass flow path (49) communicating with the upstream common chamber at an end of the upstream common chamber in the first direction and the downstream common chamber at an end of the downstream common chamber in the first direction, and a pressure damper (8) provided in the bypass flow path.
