Abstract
An inkjet printer head and fabricating method thereof are disclosed. An inkjet printer head, which includes: a lower board, in which a nozzle part and a restrictor are formed; an upper board attached to an upper portion of the lower board, in which an ink chamber and an ink inlet are formed; and a piezoelectric element joined to a membrane of the upper board, where the membrane is formed by the portions remaining after portions of the upper board are removed to form the ink chamber, is formed by attaching two boards by an attachment method that does not use a separate adhesion material, such as anodic bonding, for a simple and easy attachment, and for a strong head structure in which there are no chemical or physical reactions that may occur in adhesion layers.
