An inkjet printhead includes a cavity unit that includes: a plurality of nozzles arranged in at least one row in a first surface of the cavity unit; at least one common ink chamber extending along the row of the nozzles so as to distribute therefrom ink to the nozzles; and an ink introducing passage having an entrance on a second surface of the cavity unit which is opposite to the first surface, and extending toward the first surface to be connected to a first one of two opposite longitudinal end portions of the common ink chamber so as to introduce ink into the common ink chamber. An uppermost stream point, in terms of ink flow, in a bottom surface of the common ink chamber is located, as seen in a direction perpendicular to a direction in which the ink introducing passage extends as well as a longitudinal direction of the common ink chamber, on a side of a second longitudinal end portion of the common ink chamber, with respect to an end point of the entrance of the ink introducing passage, which end point is on the side remote from the second longitudinal end portion.
