Abstract:
A liquid ejection head including a flow path unit is provided. The flow path unit includes a plurality of liquid ejection ports arranged in a matrix form in a two-dimensional area of a parallelogram, and a plurality of pressure chambers communicating with the plurality of liquid ejection ports, respectively, and each pressure chamber being long in a first direction. The flow path unit is long in a second direction. Each of the pressure chambers has a length in the second direction larger than a length in a direction orthogonal to the second direction. The plurality of pressure chambers are arranged in a matrix form in a substantially same area as the two-dimensional area.
