When a predetermined voltage is applied between electrodes ( 302 ), metal ions deposit in a solid electrolyte ( 308 ), and thereby a conduction channel ( 310 ) is formed therein. The solid electrolyte switch ( 300 ) is thus turned on. Because this deposition mechanism is reversible, application of reverse voltage between the electrodes of the solid electrolyte switch ( 300 ) already turned on makes the deposited metal atoms to migrate in the solid electrolyte to thereby thin the conduction channel 300 , thereby the channel finally disappears, and the solid electrolyte switch ( 300 ) is turned into a non-conductive state. Use of this switch successfully realizes an IC tag which can automatically be nullified without artificial nullification.
