Abstract
A liquid ejection head includes a plurality of pressurizing chambers connected to a plurality of ejection holes, a plurality of first individual flow paths connected to the plurality of pressurizing chambers, a plurality of second individual flow paths and a plurality of third individual flow paths, a first common flow path is connected in common to the plurality of first and plurality of second individual flow paths, and a second common flow path is connected in common to the plurality of third individual flow paths. The first and second individual flow paths are connected to the same pressurizing chamber, the first individual flow path is connected to the first common flow path in an opening end portion, compared to the second individual flow path. The first individual flow path is located opposite to a side where the ejection hole is open outward, compared to the second individual flow path.
