PURPOSE:To narrow an interval between dot patterns and to improve resolution, by a method wherein a device is constituted into a multistructure in which flow path plates, having at least one flow path, are overlapped with each other, and a piezoelectric element is mounted to each flow path plate in a position corresponding to the pressure chamber of the flow path plate located in the under surface thereof. CONSTITUTION:A cooperative ink chamber 43 and an ink feed port 44 are formed in a substrate 42, and performations 48, 53, and 58, serving as pressure chambers 49, 52, and 57 and the cooperative ink chamber, are formed in first, second, and third flow path plates 46, 50, and 56, respectively. Piezoelectric elements 51, 59, and 63 are located to the under surfaces of the second and third flow path plates 50 and 56 and in spots positioned facing and opposite to the pressure chambers, 49, 52, and 57, and an aperture 60 is provided in the third flow path plate 56 and apertures 64 and 65 are formed in a seal plate 62 in order to remove the electrodes of the piezoelectric elements. The flow path plates are overlapped with the seal plate 62, thereby obtaining a nozzle train having a narrow interval between dot patterns. |
