ヘツド。[Claims for Utility Model Registration] A plurality of electrical resistors are arranged on a substrate, partitions are formed between the resistors to form ink chambers corresponding to the resistors, and a nozzle plate is placed on the substrate via the partitions. In an inkjet printhead in which ink is ejected from a nozzle by the heat generated by a resistor, the surface of the substrate containing the resistor is coated with an insulating protective film, and a conductive film is placed at a desired position on the protective film. The inkjet print head is constructed by providing a metallic film, forming the partition wall made of a metal material by plating on the metal film, and pasting a flat nozzle plate on the partition wall.

Claims

[Scope of utility model registration request]
