PROBLEM TO BE SOLVED: To provide, in a substrate including a plurality of nozzle arrays, a liquid discharge head that suppresses a deterioration in impact accuracy of ink by suppressing distortions of the nozzle arrays at both ends due to heat energy.SOLUTION: A liquid discharge head includes a substrate 110, a flow path formation member 111 stacked on the substrate 110, a plurality of discharge ports 10 formed in the flow path formation member 111, and a plurality of liquid flow paths 30 formed in the flow path formation member 111 and respectively communicating with the discharge ports 10. The liquid discharge head further includes a plurality of energy generation devices (heaters 40) arranged in the substrate 110 for generating heat energy and a plurality of liquid supply ports (ink supply ports 60) having a lengthwise direction and a widthwise direction and each supplying a liquid to some of the plurality of liquid flow paths 30. The substrate 110 has a plurality of beams 61, positioned inside the liquid supply ports provided at least at both ends of the substrate 110 and along the widthwise direction of the liquid supply ports, formed therein. |
