A method for manufacturing an ink-jet head is disclosed. The method for manufacturing an ink-jet head including a chamber containing an ink, a reservoir connected with the chamber and supplying the ink to the chamber, a restrictor connected with the chamber and the reservoir and controlling a flow of the ink, a nozzle connected with the chamber and jetting the ink, and a channel connecting the nozzle to the chamber, may include: forming the chamber, the reservoir, the restrictor and the channel by etching a portion of a substrate; covering the chamber; and bonding a nozzle plate, in which a nozzle is formed, to the substrate such that the channel is covered. Using this method, the various structures of the ink-jet head may be formed by etching a substrate, whereby the process may be simplified, and the yield and reliability of the products can be improved.
