Liquid ejection head

A liquid ejection head comprising:

• a flow path unit which 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,
• wherein the flow path unit is long in a second direction,
• wherein the second direction comprises a main scanning direction,
• wherein each of the pressure chambers has a length in the second direction larger than a length in a direction orthogonal to the second direction, and
• wherein the plurality of pressure chambers are arranged in a matrix form in a substantially same area as the two-dimensional area.
