Abstract
A resonator and a filter that can be miniaturized and highly integrated are provided. In the invention, a resonator wherein parts of resonators, support sections, and joint sections are mutually shared is formed. The mutual configuration is selectively switched as required and a large number of frequencies can be selected in the same filter unit. The resonators, the support sections, and the joint sections different in size and shape are used in combination, whereby a filter unit having a large number of selective frequencies is provided.
