Provided is a method for manufacturing an ink-jet head, wherein a residue of a sacrificial layer is prevented from being left in an ink chamber at the time of removing the sacrificial layer, and the volume of the ink chamber can be accurately maintained. Also provided is an ink-jet head. A board-like substrate (11), and a heater (13) formed on one surface of the substrate (11) are prepared. Then, one surface of the substrate (11) has formed thereon: a sacrificial layer (16), which is provided at a position that corresponds to an ink flow channel; a flow channel wall (15), which includes at least the sacrificial layer (16) and the heater (13), and which partitions an ink chamber (CH); and a nozzle layer (17), which is provided on the flow channel wall (15) and the sacrificial layer (16). Then, a jetting port (A), from which an ink is to be jetted, is formed in the nozzle layer (17). Then, the sacrificial layer (16) is removed by taking out the sacrificial layer (16) to the outside of the ink chamber (CH) through the jetting port (A). Then, an ink supply port (B) that penetrates the substrate (11) from the other surface thereof to the one surface is formed from the other surface by etching.
