    摘要: A liquid discharge head comprises a separation member for separating the discharge liquid flow paths communicated with discharge ports for discharging discharge liquid to enable discharge liquid to flow, and the bubbling liquid flow paths to enable bubbling liquid to flow, which is provided with the bubble generating areas for creating bubbles used for discharging discharge liquid from the discharge ports. This separation member is provided with the opening portions positioned to face the bubble generating areas, and displacement members provided for the separation member corresponding to the openings, having the free ends to be displaced by bubbles created on the bubble generating areas provided for the separation member. Then, with no bubbles created on the bubble generating areas, the displacement members interrupt the opening portions, and with bubbles created thereon, the free ends of the displacement members are displaced to discharge discharge liquid from the discharge ports of the head. Hence, this head can prevent discharge liquid from entering around the heat generating members at the time of bubble disappearance, and the mixture of discharge liquid and bubbling liquid when the head is left intact for a long time, while maintaining the excellent discharge efficiency by means of the displacement members thus arranged.
