Claims

[Scope of utility model registration request]

(1) An upper assembly consisting of an upper substrate having an ink supply port penetrating the substrate, a charging electrode attached to the upper substrate, an upper deflection electrode attached to the side opposite to the drop generator of the charging electrode, and a gutter. A lower substrate attached to one end, a drop generator attached to a position corresponding to the ink supply port on the lower substrate, and a drop generator paired with the upper deflection electrode on the lower substrate to perform a deflection action. and a lower assembly comprising a lower deflection electrode mounted at a position such that the upper assembly is fixed to the lower assembly via the drop generator.

(2) The inkjet print head according to claim 1, wherein at least a portion of the charged electrode facing the path through which the droplets generated by the drop generator pass is electrically conductive.
