Abstract
A high dielectric constant element suitable for making a coaxial line shape resonator comprises a number of sheets, for instance, of mica or plastic, each having plural pieces of conductive film or electrodes provided on one face with appropriate small gaps inbetween, the sheets being assembled in a pile to form a high dielectric constant element body that has high equivalent .epsilon. value without using a conventional high dielectric constant ceramic body. Fine adjustment of the resonance frequency of the coaxial line shape resonator is easily made by adjusting number of sheets per length.
