ABSTRACT:
In order to provide a low-cost large substrate for full multi-bubble-jet head, a method for manufacturing an ink-jet head in which ink-discharge-pressure generation elements are provided on a substrate, discharge ports are disposed in a plate facing the ink-discharge-pressure generation elements, and ink is discharged from the discharge ports by generating bubbles within ink includes the steps of forming a threaded port, serving as an ink supply port, in a ceramic substrate, filling the threaded ports with a filler by melting the filler, flattening a portion of the threaded port filled with the filler in the substrate, depositing a silicon nitride film on the surface of the substrate in which the portion of the threaded port is flattened, depositing a layer made of a high-heat-conduction material on the silicon nitride film, forming the ink-discharge-pressure generation elements on the high-heat-conduction layer, forming ink discharge portions having the corresponding discharge ports on the substrate having the ink-discharge-pressure generation elements, and removing the filler from the substrate having the ink discharge portions.
