Abstract: A liquid jet head manufacturing method, a method for integrally manufacturing a liquid jet apparatus, a liquid jet head, a printing apparatus and a liquid jet apparatus. The manufacturing method includes: forming multiple pressure-generating members arranged spaced apart on a first substrate; forming, on a first surface of first substrate, pressure chambers corresponding to multiple pressure-generating members, and a common chamber in communication with multiple pressure chambers; forming a transition layer on pressure chambers, and forming a jet orifice plate on transition layer; and forming, on jet orifice plate and transition layer, jet orifices in communication with pressure chambers. When the number of pressure chambers needs to be increased, since pressure chambers are formed on first substrate individually, mechanical strength of first substrate will not be reduced, and during manufacturing process, breakage of first substrate can be avoided, improving yield of liquid jet head, and reducing manufacturing cost.
