PROBLEM TO BE SOLVED: To provide a continuous discharge type multi-orifice inkjet apparatus having high reliability, high maintenance performance and high stability. SOLUTION: (1) The continuous discharge type multi-orifice inkjet apparatus is constituted of two housings, i.e., a first housing which has a liquid chamber and an orifice port, and a second housing constituting a vibration means. (2) Resonant members are separated from a vibration member by a diaphragm, and are arranged on the opposite side and the outside of a liquid chamber. (3) A structure for optimizing a resonant frequency by the resonant members and a stepped structure of the liquid chamber forms the basics of the continuous discharge type multi-orifice inkjet apparatus.
