Patent ID: 8087759

Claim:
A print head comprising: ejection ports configured to eject liquid; pressure chambers communicating with the ejection ports, the pressure chambers including a first pressure chamber and a second pressure chamber; flow paths through which liquid flows from a liquid supply port to the pressure chambers, a width of each of the flow paths at a connecting portion where one of the pressure chambers and the flow path are connected is smaller than a width of the one of the pressure chambers at the connecting portion, the flow paths including a first flow path and a second flow path which is shorter than the first flow path; and print elements provided in each of the pressure chambers to generate energy for ejecting liquid from the ejection ports, a center of each of the print elements along a liquid supply direction from a corresponding one of the flow paths to a corresponding one of the pressure chambers is offset from a center of the corresponding one of the pressure chambers in the liquid supply direction, the print elements including a first print element provided in the first pressure chamber and a second print element provided in the second pressure chamber, wherein an offset amount between the centers of the first pressure chamber and the first print element in the first pressure chamber through which liquid flows from the first flow path is smaller than the offset amount between the centers of the second pressure chamber and the second print element in the second pressure chamber through which liquid flows from the second flow path.
