Abstract

To provide a liquid dispenser that improves foam quality without increasing costs or reducing usability. [Solution] The generating chip has an inner cylinder portion that extends axially, is located on one side in the axial direction from the first end, is positioned radially inward from the outer cylinder portion, and has a bubble nozzle on the inside, and an extension portion that is positioned between the first end and the inner cylinder portion in the axial direction, and extends from the inner wall of the outer cylinder portion to a position radially inward from the outer wall of the cylinder portion. The inner cylinder portion forms a first outside air intake port that extends axially between itself and the outer cylinder portion, and the extension portion has an airflow regulating surface on one side in the axial direction facing the first outside air intake port, and the airflow regulating surface forms a second outside air intake port that extends radially inward and opens between itself and the second end on the other side in the axial direction of the inner cylinder portion.
