Abstract

A liquid ejection head includes pressure chambers arranged in a first direction and respectively communicating with nozzles, pairs of upstream and downstream flow paths extending in a second direction different from the first direction, each pair communicating with a pressure chamber, the upstream path connected to a first end of the corresponding chamber, and the downstream path of said each pair connected to a second end of the chamber, an upstream common chamber communicating with the upstream paths, a downstream common chamber communicating with the downstream paths, and a bypass flow path communicating with the upstream chamber at an end thereof and the downstream chamber at an end thereof. Each upstream path has an inlet connected to the upstream chamber and an outlet connected to the corresponding chamber, the inlet widening toward the end of the upstream chamber.
