Liquid ejecting head and liquid ejecting system

A liquid ejecting head comprising:

• a plurality of nozzles that discharge a liquid in a first axis direction;
• first and second common liquid chambers that communicate in common with the plurality of nozzles;
• and
• a plurality of individual flow paths coupling the first common liquid chamber to the second common liquid chamber, wherein each individual flow path is provided for each of the nozzles, communicates with the nozzle disposed between the first common liquid chamber and the second common liquid chamber, wherein
• each individual flow path includes a pressure chamber provided with an energy generation element, and an individual communication flow path coupling the pressure chamber to the first and second common liquid chambers,
• a plurality of the pressure chambers are arranged side by side in a second axis direction orthogonal to the first axis direction to form first and second pressure chamber rows, and the first pressure chamber row and the second pressure chamber row are disposed to be shifted relative to each other in a third axis direction orthogonal to the first axis direction and the second axis direction when viewed in the second axis direction,
• each individual communication flow path corresponding to the first pressure chamber row has a first portion and a second portion,
• each individual communication flow path corresponding to the second pressure chamber row has a third portion,
• each first portion corresponding to the first pressure chamber row is arranged in the second axis direction and interposed between two third portions corresponding to the second pressure chamber row,
• each second portion corresponding to the first pressure chamber row is also arranged in the second axis direction, but not interposed between any portion of individual communication flow paths corresponding to the second pressure chamber row, and
• in the individual communication flow path, a maximum width of the second portion in the second axis direction is larger than a maximum width of the first portion in the second axis direction.
