Patent ID: 8534796

Claim:
A liquid-discharging recording head comprising: a plurality of 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 closest to a first end of the support member in the longitudinal direction, and a second substrate provided closest to a second end of the support member opposite the one end in the longitudinal direction, wherein the plurality of substrates includes a region overlapping with regions of adjacent substrates in the longitudinal direction, wherein a distance between the supply port in the first substrate and an end, on a side of the first end, of the first substrate is smaller than a distance between the supply port in the first substrate and an end, on a side of the second end, of the first substrate, wherein a distance between the supply port in the second substrate and an end, on a side of the second end, of the second substrate is smaller than a distance between the supply port in the second substrate and an end, on a side of the first end, of the second substrate, and wherein a region between the supply port in the first substrate and the end, on a side of the second end, of the first substrate and a region between the supply port in the second substrate and the end, on a side of the first end, of the second substrate each includes a driving circuit configured to drive the energy generating element.
