Abstract
A small-size electromechanical filter that can be highly integrated and can be tuned is provided. An electromechanical filter includes a conductor acting as a signal line (movable electrode)a magnetic field generating portionfor generating a magnetic field passing through the conductor, and a drive electrodefor changing the magnetic field passing through the signal line by displacing relative positions of the conductor and the magnetic field generating portion, whereby a tuning of a ferromagnetic resonance frequency, which is difficult to realize in the prior art, can be realized by changing the magnetic field passing through the signal line.
