Abstract
In a dielectric resonator device, electrodes having electrode non-formation sections opposite to each other and having substantially the same shape and size are formed on the opposite main faces of a dielectric plate. The portion of the dielectric plate sandwiched between the electrode non-formation sections opposite to each other is used as a dielectric resonator section. Further, the characteristics of the dielectric resonator device are adjusted by attaching dielectric chips inside of the dielectric resonator section or between adjacent dielectric resonator sections.
