Mems switch and communication device using the same

Abstract

A MEMS switch is provided, wherein contact force sufficient to make a contact having low contact resistance is maintained after contact-formation to maintain low contact resistance at the contact where the signal is transmitted in “on” state. Provided is a MEMS switch 100 including a first electrode 101, a second electrode 104 opposed to and separated from the first electrode, a third and a fourth electrodes 1021 and 1022, wherein electrical contact is made between the electrode 101 and the electrode 104 by electrostatic force generated between the electrode 101 and the electrodes 1021, 1022, and a bump which can form the contact between the electrode 101 and the electrode 1021 and/or 1022 is provided on the electrode 101, and a gap is formed between the electrode 101 and the electrode 1021 and/or 1022 when the electrical contact is made between the electrodes 101 and 104.
