Abstract
A high frequency filter Ahas frequency characteristics such that the amount of attenuation for an input electrical signal is smaller in a first frequency band fthan in a second frequency band f. The high frequency filter Ais provided with a dielectric elastomer transducerthat includes a dielectric elastomer layerand a pair of electrode layerssandwiching the dielectric elastomer layer. The frequency characteristics are variable by the dielectric elastomer transducer. This configuration provides a high frequency filter having frequency characteristics that are variable and suitable for a lightweight and compact configuration.
