摘要:
An ink-jet recording head having no piezoelectric element in a part where no piezoelectric element is required and including an individual electrode lead-out part having such a cross section that allows smooth power supply is provided. The ink-jet recording head includes an individual electrode having an individual electrode main body formed at a position corresponding to an ink chamber and an individual electrode lead-out part for supplying power, a piezoelectric element formed to contact the individual electrode, and a diaphragm formed to contact the piezoelectric element. The individual electrode lead-out part is connected to the individual electrode main body from a position offset from a face including an electrode face of the individual electrode main body, and the piezoelectric element is formed into a shape corresponding to the individual electrode main body.
