Abstract:
There is provided a liquid ejection head capable of performing high-speed ejection operation as well as reducing a depth dimension. For this purpose, in a configuration in which flexible circuits electrically connect element substrates to electrical substrates, the electrical substrates are arrayed in two lines along a plane different from a plane on which the element substrates are arrayed and the flexible circuits electrically connect the element substrates to the electrical substrates while being bent.

Claim (Index 18):
An inkjet printing apparatus to print an image on a print medium by ejecting ink based on an ejection signal by the use of an inkjet printing head,\n the inkjet printing head comprising: a plurality of element substrates on which elements configured to eject ink are arrayed; a plurality of electrical substrates each equipped with a first terminal and configured to supply power and an ejection signal to the plurality of element substrates; and a plurality of flexible circuits each equipped with a second terminal electrically connected to the first terminal and configured to connect the element substrate to the electrical substrate electrically, wherein the plurality of electrical substrates form electrical substrate arrays along a plane different from a plane on which the plurality of element substrates are arrayed, and extending in a direction in which the plurality of element substrates are arrayed, each of the flexible circuits electrically connects the element substrate to the electrical substrate while being bent, the plurality of electrical substrate arrays include two electrical substrate arrays arranged such that at least parts of first surfaces of the electrical substrates are opposed to each other, and electrical connection portions between the first terminals and the second terminals are provided on second surfaces which are back surfaces of the first surfaces of the electrical substrates.
