Abstract:
A relay device comprising an opposing terminal section, and a driving unit provided opposingly to one side of said opposing terminal section and including a number of actuator elements arranged corresponding to a large number of switching elements, for switching and controlling ON/OFF operation of said switching element by controlling displacement action of each of said actuator elements in a direction to make contact or separation with respect to said opposing terminal in accordance with an attribute of a driving signal to be inputted, wherein said actuator element comprises:a main actuator element having an anti-ferroelectric film and at least a pair of electrodes formed on said anti-ferroelectric film; a vibrating section for supporting said main actuator element; and a fixed section for vibratingly supporting said vibrating section, said relay device further comprising: a signal terminal section for transmitting, to said opposing terminal section, said displacement action of said actuator element generated by applying a voltage to said pair of electrodes.
