Abstract
Official abstract text for this publication.
A liquid discharge head includes a substrate including an energy generating element that generates energy used to discharge liquid and a discharge port member having a discharge port surface with a discharge port line including discharge ports, through which the liquid is discharged, arrayed in a first direction. The discharge port surface includes a groove portion disposed between the discharge port line and a first end of the discharge port member in a second direction intersecting the first direction. The groove portion extends along the discharge port line. The discharge port surface further includes an inclined surface disposed between an end of the discharge port line and a second end of the discharge port member in the first direction. The inclined surface is inclined toward the second end.
