PROBLEM TO BE SOLVED: To provide an ink jet head having a vibrating plate which especially effectively transmits the mechanical displacement of a piezoelectric body element, and is high in performance and reliability and a pressure chamber member having a pressure chamber which is high in assembling precision and small in variation, in order to attain miniaturization and high density of the ink head jet, and to provide a manufacturing method of the ink jet head, and an ink jet system recorder. SOLUTION: The ink jet head includes the piezoelectric body element (piezoelectric body element section B), the vibrating plate 3 provided on the piezoelectric body element, and the pressure chamber member A which is provided on the side opposite to the piezoelectric body element of the vibrating plate 3 and stores ink. The vibrating plate 3 is configured in such a manner that at least two different materials are stacked in a film thickness direction and the portion (second vibrating plate 3b) in contact with the ink of the vibrating plate 3 and the pressure chamber member A are made of materials containing same main components.
