Patent ID: 8083317

Claim:
A liquid-discharging recording head comprising: two substrates each including an energy generating element configured to generate energy used to discharge liquid and a supply port configured to supply the liquid to the energy generating element; and a support member on which the substrates are arranged to extend along each other in a longitudinal direction, wherein the substrates include a first substrate provided on one side of the support member in the longitudinal direction, and a second substrate provided on an other side of the support member opposite the one side in the longitudinal direction, wherein a region of the first substrate on the other side overlaps with a region of the second substrate on the one side in a direction intersecting the longitudinal direction, wherein a distance between an end of the supply port in the first substrate on the one side in the longitudinal direction and an end of the first substrate on the one side is smaller than a distance between an end of the supply port in the first substrate on the other side in the longitudinal direction and an end of the first substrate on the other side, wherein a distance between an end of the supply port in the second substrate on the other side in the longitudinal direction and an end of the second substrate on the other side is smaller than a distance between an end of the supply port in the second substrate on the one side in the longitudinal direction and an end of the second substrate on the one side, and wherein a region between the end of the supply port in the first substrate on the other side in the longitudinal direction and the end of the first substrate on the other side and a region between the end of the supply port in the second substrate on the one side in the longitudinal direction and the end of the second substrate on the one side each includes a driving circuit configured to drive the energy generating element.
