发明名称 LIQUID DISCHARGE HEAD AND LIQUID DISCHARGE HEAD DEVICE
摘要 A liquid discharge head includes an energy generating element which generates energy to be used to discharge a liquid; and a plurality of discharge ports which is formed for each energy generating element and allows the liquid to be discharged therethrough. The plurality of discharge ports have regions where the angles of contact with the liquid are different around the discharge ports, and the regions in the discharge ports where the contact angles are relatively small are formed at different positions in the plurality of discharge ports, and the liquids discharged from the plurality of discharge ports are discharged in directions away from each other.
