PROBLEM TO BE SOLVED: To provide a switching element which causes a heavy current to be flowed although being small-sized. SOLUTION: In a liquid 3 in which particles are dispersed, a pair of electrodes 41, 42 are disposed while facing to each other at a predetermined facing interval D1. By applying a high frequency voltage between the pair of electrodes 41, 42, dielectrophoresis of particles is performed in the liquid 3 to bridge between the electrodes 41, 42 to achieve a conduction state (Fig.(b)). By stopping applying the high frequency voltage between the pair of electrodes 41, 42, dielectrophoresis of particles is stopped, and bridging between these electrodes 41, 42 is destroyed to cancel the conduction state (Fig.(a)). Thus, ON/OFF of a switch is changed over in accordance with the presence or absence of applying the high frequency voltage to the electrodes 41, 42. COPYRIGHT: (C)2010,JPO&INPIT |
