Abstract
A liquid ejection head is 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.
