Liquid-discharging recording head

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 one end of the support member in the longitudinal direction, and a second substrate provided closest to the other 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 of the first substrate closest to the one end is smaller than a distance between the supply port in the first substrate and an end of the first substrate closest to the other end,
• wherein a distance between the supply port in the second substrate and an end of the second substrate closest to the other end is smaller than a distance between the supply port in the second substrate and an end of the second substrate closest to the one end, and
• wherein a region between the supply port in the first substrate and the end of the first substrate closest to the other end and a region between the supply port in the second substrate and the end of the second substrate closest to the one end each includes a driving circuit configured to drive the energy generating element.
