A high-speed, high-resolution inkjet printhead. At least two ink-supply paths used to supply ink to the ink chamber are arranged on the substrate in a two-dimensional array. The present invention overcomes the disadvantages of conventional inkjet printheads, i.e., low degree of integration arising from nozzles aligned in a line around a single ink-supply path. Thus, according to the present invention, a large number of nozzles can be integrated on the substrate, thus resulting in high-speed, high-resolution printing.
