Inkjet print head and method of manufacture therefor

A method of manufacturing an inkjet printhead which comprises a substrate, actuators varying a volume of a pressure chamber, each actuator composing of a piezoelectric material, each actuator being adhered to the substrate and forming a sidewall that isolate the respective pressure chambers, an electrode composing of a metal film provided on the sidewall, a wiring part connected to the electrode, and a non-wiring part provided between the adjacent wiring parts, the method comprising:

• adhering a substrate and an piezoelectric material together;
• processing the piezoelectric material to form a groove therein;
• forming a resist film on the adhesive between the substrate and the piezoelectric material, resist film forming the non-wiring part;
• forming a metal film on the sidewall and substrate, the metal film as being the electrode and the wiring part;
• forming the non-wiring part by laser processing excluding a portion formed by the resist film, and
• removing the resist film.

An inkjet printhead, comprising:

• a substrate;
• actuators for varying a volume of a pressure chamber, each actuator having an obliquity angle at their ends in an ink flow direction within the pressure chamber and forming a sidewall that isolate the respective pressure chambers, and composing of a piezoelectric and forming sidewalls that isolate the respective pressure chambers;
• an adhesive layer for fixing the actuators to the substrate;
• an electrode composing of a metal film provided on the sidewall;
• a wiring part composing of the metal film connected to the electrode;
• a connecting part composed of the metal film, formed on the adhesive layer, for connecting the electrode and the wiring part;
• a first non-wiring part provided between electrodes formed on the adjacent sidewalls and between the adjacent wiring parts;
• and
• a second non-wiring part formed between the adjacent connecting parts in a method different from the method of forming the first non-wiring part.
