PROBLEM TO BE SOLVED: To provide a drop discharge device which is easy of nozzle replacement and washing without exposing liquid to a high temperature and a high pressure and can be driven at a high frequency by a low voltage. SOLUTION: In the drop discharge device 1, by the change in a magnetic field generated by a fixed primary coil 210, and an induction current is produced in a cylindrical conductive member 230 which is a secondary coil. By the interaction between the induction current and a static magnetic field applied in advance by an annular magnetic circuit 220, the member 230 is moved in the liquid discharge direction. The member 230 is formed as a movement member 140 integrally with the front 122 of a liquid chamber 130. When the member 230 is moved, the front 122 with a discharge opening 123 formed is moved to change the volume of the liquid chamber 130 storing the liquid to be discharged. As a result, the liquid stored in the liquid chamber 130 is pressurized to be discharged from the opening 123. COPYRIGHT: (C)2004,JPO&NCIPI
