Patent ID: 7531940

Claim:
An ion introducer, characterized in comprising: an oscillator comprising a piezoelectric bimorph element which has at least two piezoelectric elements and which is configured to produce an electromotive force by imparting a stress to each of the piezoelectric elements, the piezoelectric bimorph element being arranged to deform in a direction in which the electromotive force is created: good electrical conductors connected to each of the at least two piezoelectric elements, from which the piezoelectric bimorph element is formed, which serve as an anode and a cathode when the electromotive force produced by stress deformation of the piezoelectric bimorph element is generated; and a rectifier connected to link the good electrical conductors, an electrode configured from a good conductor having a predetermined surface area being connected to the good electrical conductor connected to a positive electrode terminal of the rectifier, and an electrode configured from a good conductor having a predetermined surface area being connected to the good electrical conductor connected to a negative electrode terminal of the rectifier, and at least one of these electrodes being configured to oscillate in synchronization with the oscillator.
