Abstract
A high frequency filter A1 has frequency characteristics such that the amount of attenuation for an input electrical signal is smaller in a first frequency band f1 than in a second frequency band f2. The high frequency filter A1 is provided with a dielectric elastomer transducer 1 that includes a dielectric elastomer layer 13 and a pair of electrode layers 14 sandwiching the dielectric elastomer layer 13. The frequency characteristics are variable by the dielectric elastomer transducer 1. This configuration provides a high frequency filter having frequency characteristics that are variable and suitable for a lightweight and compact configuration.
