PROBLEM TO BE SOLVED: To provide a liquid discharge head which can more reliably suppress pressure variations in individual liquid chambers from propagating, thereby solving a problem that it is impossible to sufficiently suppress pressure variations in individual flow channels from propagating by only providing a damper region in a common liquid chamber.SOLUTION: A flow channel plate is provided with individual flow channels 5 which are formed on it and include a liquid supply passage 70 constituted of an individual liquid chamber 6, a fluid resistance part 7 and a liquid introduction part 8. Buffer chambers 41 holding gas are provided between the fluid resistance parts 7, 7 of the flow channel plate, and the buffer chambers 41 are connected with the liquid introduction parts 8 via passages 42. The cross-sectional area of the opening of the passages 42 connecting the buffer chambers 41 and the liquid introduction parts 8 is smaller than the cross-sectional area of the opening of the liquid introduction parts 8. |
