摘要：
An ink print head reducing ink supply errors caused by air bubbles in order to stably supply ink at larger amounts. The ink print head includes an ink container for holding ink, a recording element for discharging the ink supplied from the ink container, a duct disposed between the ink container and the recording element to transfer the ink to the recording element, and an inductive channel which communicates with the duct. The inductive channel transfers the ink to the recording element from the ink container, and has a capillary force greater than that of the duct.
