<p><P>PROBLEM TO BE SOLVED: To provide an actuator which is provided with rigidity so that contacts are not agglutinated to each other. <P>SOLUTION: A switching device includes a contact part in which a first contact is provided, and the actuator which moves a second contact to come into contact with or to be separated from the first contact. The actuator includes: a laminated first piezoelectric film and second piezoelectric film; a first insulating layer provided on the surface side opposite to the second piezoelectric film in the piezoelectric film; and a second insulating layer provided on the surface side opposite to the first piezoelectric film in the second piezoelectric film. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
